CDS2 Antibody, HRP conjugated is a polyclonal antibody raised in rabbits that specifically targets the human Phosphatidate cytidylyltransferase 2 protein (CDS2). This antibody has been directly conjugated to horseradish peroxidase (HRP), an enzyme that catalyzes the oxidation of substrates in the presence of hydrogen peroxide, resulting in either colorimetric or chemiluminescent signals. The target protein, CDS2, is involved in signal transduction pathways and functions as CDP-DAG synthase 2, CDP-DG synthase 2, or CDP-diacylglycerol synthase 2 (EC 2.7.7.41) . This enzyme plays a crucial role in phospholipid biosynthesis and cellular signaling processes, making it a significant target for research in cell biology and signal transduction studies.
The CDS2 Antibody, HRP conjugated (Product Code: CSB-PA005123LB01HU) has the following specifications: it is generated against the recombinant Human Phosphatidate cytidylyltransferase 2 protein (specifically amino acids 354-445), has high purity (>95% as verified by Protein G purification), and is supplied in liquid form . The storage buffer consists of 0.03% Proclin 300 as a preservative, 50% Glycerol, and 0.01M PBS at pH 7.4 . The antibody is of IgG isotype and has been tested specifically for ELISA applications. Its UniProt accession number is O95674, corresponding to the human CDS2 protein . These specifications ensure high reliability and reproducibility in research applications focused on human CDS2 protein detection.
The HRP conjugation mechanism involves the covalent attachment of horseradish peroxidase enzyme molecules to the antibody structure without compromising its antigen-binding capabilities. This enzymatic conjugation provides signal amplification during detection procedures. When the antibody binds to its target (CDS2 protein), the attached HRP enzyme catalyzes the oxidation of various substrates in the presence of hydrogen peroxide . This reaction produces either a colored precipitate (in chromogenic detection) or light emission (in chemiluminescent detection), depending on the substrate used . The primary advantage of HRP conjugation is the significant signal amplification it provides, allowing for the detection of even low-abundance proteins with high sensitivity. This direct conjugation also eliminates the need for a secondary detection antibody, streamlining experimental protocols and potentially reducing background signal issues that can occur in multi-step detection procedures.
The manufacturer recommends storing CDS2 Antibody, HRP conjugated at either -20°C or -80°C upon receipt . It is crucial to avoid repeated freeze-thaw cycles as these can compromise antibody activity and stability. The antibody is supplied in a specialized buffer containing 50% glycerol, which helps maintain stability during frozen storage . For working solutions, refrigeration at 2-8°C is appropriate for short-term use (typically 1-2 weeks), but aliquoting the stock solution before freezing is strongly advised for antibodies that will be used multiple times. This practice minimizes freeze-thaw cycles that can lead to denaturation of the antibody protein structure and deterioration of the HRP enzyme activity. Additionally, protection from light is recommended as HRP conjugates can be light-sensitive, particularly when diluted for use in experimental procedures. Proper storage is essential to maintain both antigen recognition capabilities and enzymatic activity of the HRP component.
The CDS2 Antibody, HRP conjugated undergoes rigorous purification via Protein G affinity chromatography, achieving >95% purity . This purification method specifically selects for IgG antibodies, removing contaminants that could interfere with specific binding. Quality control testing includes validation specifically for ELISA applications to ensure functional activity of both the antibody's antigen-binding capability and the conjugated HRP enzyme . The antibody is produced against a defined region of the human CDS2 protein (amino acids 354-445), enhancing epitope specificity . While the search results don't explicitly mention additional validation methods, standard industry practices for polyclonal antibodies typically include assessment of lot-to-lot consistency, specificity testing against the immunogen, and verification of HRP enzymatic activity using standard substrates. Researchers should consult the Certificate of Analysis (CoA) provided with each lot for specific performance metrics and consider performing their own validation in their experimental systems.
Optimizing CDS2 Antibody, HRP conjugated for ELISA requires systematic adjustment of several parameters to achieve maximum sensitivity and specificity. Begin with a titration experiment using a dilution series (typically 1:500 to 1:10,000) of the antibody against known positive and negative controls to determine the optimal working concentration . The buffer composition significantly impacts performance—PBS with 0.05% Tween-20 and 1-5% blocking protein (BSA or casein) typically yields good results, while avoiding phosphate buffers when using phospho-specific antibodies. Incubation time and temperature should be empirically determined; standard conditions include 1-2 hours at room temperature or overnight at 4°C . The detection substrate must be compatible with HRP; common options include TMB (3,3',5,5'-tetramethylbenzidine) for colorimetric detection or luminol-based reagents for chemiluminescence, with the latter offering greater sensitivity for low-abundance targets . Multiple washing steps (4-5 times) with PBS-Tween between each incubation are critical to reduce background. Finally, consider including positive and negative controls, as well as a standard curve using recombinant CDS2 protein, to ensure reliable quantification and interpretable results.
Addressing interference issues with CDS2 Antibody, HRP conjugated requires multiple strategies. First, implement rigorous blocking protocols using 3-5% BSA or casein in PBS-Tween to minimize non-specific binding that can lead to background signals . Pre-adsorption of the antibody with non-relevant proteins can significantly reduce cross-reactivity. For sample preparation, consider pre-clearing complex biological samples through centrifugation or filtration to remove particulates and aggregates that may cause non-specific binding. Hemolysis, lipemia, and high biotin concentrations in samples can interfere with HRP activity—these should be avoided or controlled for with appropriate sample preparation techniques. Some endogenous enzymes (particularly peroxidases) can generate false positive signals; these can be neutralized by treating samples with hydrogen peroxide (0.3%) prior to antibody incubation . The addition of 0.01-0.05% carrier proteins or heterologous serum (from a species different from the antibody host) to the antibody diluent can reduce non-specific interactions. Finally, consider using detection systems with specialized signal enhancers designed specifically for HRP-conjugated antibodies, which can improve signal-to-noise ratios without increasing background interference.
Temperature and pH critically influence the catalytic efficiency of HRP in conjugated antibodies through multiple mechanisms. The optimal temperature for HRP activity is typically 25-30°C, with activity declining sharply above 40°C due to enzyme denaturation . At temperatures below 20°C, reaction kinetics slow significantly, requiring extended incubation times. Extended exposure to temperatures above 37°C can irreversibly damage the HRP enzyme, while repeated temperature fluctuations can cause gradual activity loss over time. Regarding pH, HRP exhibits a bell-shaped activity curve with optimal activity between pH 6.0-6.5 for most substrates, although this varies slightly depending on the specific substrate used . Activity drops precipitously below pH 5.0 and above pH 9.0, with irreversible inactivation occurring at extreme pH values. Buffer composition also impacts HRP stability—phosphate buffers at 0.1M concentration provide good stability, while certain buffer additives (sodium azide, cyanides, sulfides) can strongly inhibit HRP activity even at low concentrations. For maximum signal generation with CDS2 Antibody, HRP conjugated, maintaining reaction conditions at pH 6.0-7.0 at room temperature (20-25°C) provides the best compromise between enzyme activity and stability during experimental procedures.
Signal amplification strategies can significantly enhance detection sensitivity when using CDS2 Antibody, HRP conjugated, particularly for low-abundance targets. The tyramide signal amplification (TSA) system leverages HRP's catalytic activity to generate multiple reactive tyramide molecules that covalently bind to adjacent proteins, providing 10-100 fold signal enhancement . This approach is particularly valuable for detecting low-expression CDS2 in complex tissues. Enhanced chemiluminescent (ECL) substrate systems containing phenols and luminol derivatives with enhancers like 4-iodophenylboronic acid can increase light output by 10-50 fold compared to standard substrates . Polymer-based technologies such as poly-HRP systems attach multiple HRP molecules to each antibody, exponentially increasing detection capability. Sequential multi-layer approaches can be implemented where a biotinylated anti-HRP antibody binds to the primary HRP signal, followed by streptavidin-HRP, creating an amplification cascade. Additionally, specialized substrate incubation methods like channeling the substrate directly over the bound antibody or using microfluidic technologies enhance local substrate concentration. For quantitative measurements, researchers should note that while these amplification systems increase sensitivity, they may compress the dynamic range at higher analyte concentrations; therefore, standard curves should always be run with amplified systems to ensure accurate quantification.
Cross-reactivity with CDS2 Antibody, HRP conjugated can emerge from multiple sources and requires careful consideration. The polyclonal nature of this antibody means it contains heterogeneous immunoglobulin molecules recognizing different epitopes on the target protein, potentially increasing the chance of recognizing structurally similar proteins . Of particular concern is possible cross-reactivity with CDS1 (CDP-diacylglycerol synthase 1), which shares significant sequence homology with CDS2. Additionally, the CDS2 antibody targets amino acids 354-445 of the human protein, so researchers working with non-human samples should be especially cautious despite the antibody's stated human species reactivity . Cross-reactivity can also arise from protein modifications—phosphorylated, glycosylated, or otherwise post-translationally modified forms of CDS2 might show different binding affinities compared to the recombinant immunogen used for antibody production. Pre-adsorption against related proteins can reduce cross-reactivity, while Western blotting with positive and negative control samples provides a direct assessment of specificity. Additionally, epitope mapping studies or competitive binding assays with the specific immunogen peptide can confirm binding specificity. Researchers should always validate this antibody in their specific experimental system with appropriate controls before proceeding with critical experiments.
Optimizing western blotting with CDS2 Antibody, HRP conjugated requires methodical adjustment of multiple parameters. Begin with sample preparation—efficient protein extraction using buffers containing protease inhibitors is crucial for preserving CDS2 integrity . For membrane transfer, nitrocellulose membranes typically provide optimal binding for the ~55 kDa CDS2 protein, with PVDF as an alternative for higher protein retention . An effective blocking strategy using 5% non-fat dry milk or BSA in TBST for 1-2 hours at room temperature minimizes non-specific binding. Antibody concentration optimization is critical—start with a 1:1000 dilution and adjust based on signal-to-noise ratio . Given that HRP direct conjugation eliminates the need for secondary antibodies, incubation conditions become even more important; overnight incubation at 4°C often produces cleaner results than shorter room temperature incubations. For detection, enhanced chemiluminescent (ECL) substrates are recommended for optimal sensitivity, with exposure time optimization being critical for detecting the specific band at approximately 55 kDa (the predicted molecular weight of human CDS2) . Include positive controls (human tissue or cell lysates known to express CDS2) and negative controls (tissues without CDS2 expression) in each experiment. Finally, stripping and reprobing with housekeeping protein antibodies provides loading control validation to ensure equal protein loading across samples.
Determining the optimal working dilution for CDS2 Antibody, HRP conjugated requires a systematic titration approach across multiple experimental parameters. Begin with a broad dilution series (1:100, 1:500, 1:1000, 1:5000, and 1:10000) tested against samples containing known quantities of the target protein and appropriate negative controls . For ELISA applications, the manufacturer has validated this antibody, so start with their recommended dilution range and adjust based on your specific assay format and detection system sensitivity . The optimal dilution will produce a strong specific signal while maintaining minimal background—typically the highest dilution that still produces a clearly detectable signal above background in positive samples while showing negligible signal in negative controls. Sample type significantly influences optimal dilution; cell lysates may require different antibody concentrations than tissue sections or purified proteins. The choice of detection substrate also impacts dilution optimization; more sensitive chemiluminescent substrates permit higher antibody dilutions compared to chromogenic substrates . Incubation time and temperature must be considered jointly with dilution—higher dilutions typically require longer incubation periods. Document the signal-to-noise ratio at each dilution under standardized conditions, and conduct replicate experiments to ensure reproducibility. The optimal working dilution should provide consistent results across multiple experiments and ideally fall within the linear range of detection for quantitative applications.
Comprehensive validation of CDS2 Antibody, HRP conjugated experiments requires multiple control types to ensure result reliability. Positive controls should include samples known to express CDS2 protein, such as human tissues or cell lines with verified CDS2 expression (the antibody is specifically reactive to human samples) . Negative controls should include tissues or cell lines lacking CDS2 expression or samples from CDS2 knockout models if available. An antibody isotype control (rabbit IgG-HRP with no specific target) processed identically to experimental samples helps distinguish specific binding from background Fc receptor interactions or non-specific binding . Peptide competition/blocking controls, where excess immunizing peptide (amino acids 354-445 of human CDS2) is pre-incubated with the antibody before sample application, can confirm signal specificity . Loading controls (housekeeping proteins) are essential for western blot applications to normalize signal intensity across samples. Technical controls should include substrate-only wells/membranes (no antibody) to assess background from detection reagents, and full protocol controls omitting primary antibody to evaluate non-specific binding from the detection system. For quantitative applications, standard curves using recombinant CDS2 protein at known concentrations should be included. Biological replicates (different samples of the same type) and technical replicates (same sample processed multiple times) help establish result reproducibility and reliability.
Resolving weak or absent signals with CDS2 Antibody, HRP conjugated requires systematic investigation of multiple potential issues. First, verify antibody integrity by assessing enzyme activity—place a small drop of antibody solution on filter paper and add HRP substrate; a color change indicates functional HRP . Check storage conditions, as improper storage or excessive freeze-thaw cycles can degrade both antibody and enzyme activity . For sample-related issues, ensure adequate protein concentration and confirm target protein expression in your sample type—CDS2 is differentially expressed across tissues and cell types. Enhance antigen retrieval techniques for fixed samples using heat-induced epitope retrieval (HIER) or enzymatic methods to expose antibody binding sites potentially masked during fixation. Optimize incubation conditions by extending primary antibody incubation time (overnight at 4°C) and ensuring proper buffer composition without HRP inhibitors like sodium azide . Increase detection sensitivity by switching to enhanced chemiluminescent substrates with signal amplification capabilities, and extend substrate incubation time while ensuring the substrate hasn't exceeded its shelf life . Reduce stringent washing conditions that might remove valid signal, particularly with PBS containing 0.05% rather than 0.1% Tween-20. If using western blotting, confirm adequate transfer to the membrane using reversible protein stains like Ponceau S. Consider sample preparation issues—phosphatase or protease inhibitors may be necessary to preserve the CDS2 epitope in its native form. Finally, try reducing agent concentration adjustment if detecting CDS2 under denaturing conditions, as this can affect epitope accessibility.
Adapting CDS2 Antibody, HRP conjugated for high-throughput screening requires optimization for automation, reproducibility, and miniaturization. Begin by reformatting ELISA protocols to 384- or 1536-well microplates to maximize throughput while reducing sample and reagent volumes . Automated liquid handling systems should be calibrated specifically for the viscosity characteristics of the antibody solution (containing 50% glycerol) . Signal detection optimization is critical—chemiluminescent substrates offer superior sensitivity for high-throughput applications, but require stable signal generation over the time needed to read multiple plates . For this purpose, extended-duration chemiluminescent substrates that maintain signal stability for 8-24 hours are preferable. Standardize positive and negative controls on each plate to normalize for plate-to-plate variation, with control positioning following statistical designs that account for positional effects. Implement quality control metrics including Z-factor calculations, signal-to-background ratios, and coefficient of variation analyses to ensure assay robustness across numerous samples. Data management systems should be established for handling the large datasets generated, with automated analysis pipelines incorporating signal normalization and hit identification algorithms. Antibody lot consistency becomes particularly critical in high-throughput contexts—perform bridging studies when changing lots to maintain data comparability. Finally, automated washing systems require optimization for complete well clearing without cross-contamination, which may necessitate additional washing steps compared to manual protocols.
Successful multiplexing with CDS2 Antibody, HRP conjugated requires careful consideration of detection compatibility, antibody cross-reactivity, and signal separation. When combining with fluorescently-labeled antibodies, select fluorophores with emission spectra distinct from common HRP substrates to prevent signal overlap—for instance, far-red fluorophores are ideal companions to HRP-based detection systems . Sequential detection approaches work best, typically detecting the HRP-conjugated antibody first, followed by a complete substrate depletion step, before proceeding to fluorescent detection. Multiplexing with other enzymatic systems (like alkaline phosphatase) requires substrate selection that produces spectrally distinct signals—for example, combine an HRP-driven chemiluminescent reaction with an alkaline phosphatase-driven colorimetric reaction. When detecting multiple targets on the same membrane or tissue section, ensure adequate stripping between sequential detections with HRP-conjugated antibodies to prevent residual signal carryover. Host species considerations are critical—choose companion antibodies raised in different host species than the rabbit-derived CDS2 antibody to prevent cross-reactivity . For complex multiplexing in tissue sections, tyramide signal amplification with spectrally distinct fluorophores can allow several HRP-conjugated antibodies to be used sequentially after complete HRP inactivation between steps . In automated systems, precisely timed substrate addition and imaging are essential to prevent signal contamination between detection channels. Finally, always include single-detection controls alongside multiplexed samples to verify that multiplexing doesn't compromise individual signal integrity.
Quantitative analysis of data generated with CDS2 Antibody, HRP conjugated requires rigorous analytical approaches and appropriate controls. For ELISA applications, establish a standard curve using purified recombinant CDS2 protein at known concentrations, applying appropriate curve-fitting models (four-parameter logistic regression typically provides better accuracy than linear regression) . Signal linearity assessment is essential—determine the dynamic range within which signal intensity correlates linearly with protein concentration, and ensure experimental samples fall within this range through appropriate dilution. For western blot densitometry, use digital image acquisition systems rather than film to ensure signal capture within the linear range of detection . Normalization to housekeeping proteins or total protein stains (Ponceau S, SYPRO Ruby) corrects for loading variations, with total protein stains generally providing more reliable normalization across diverse samples. Software tools with background subtraction capabilities improve quantification accuracy, especially with chemiluminescent detection systems that may have uneven background. For all platforms, technical replicates (minimum triplicate) enable statistical analysis of variability, while biological replicates address sample-to-sample variation. Statistical approaches should include outlier identification methods, normality testing, and appropriate parametric or non-parametric tests based on data distribution. For multi-group comparisons, employ ANOVA with appropriate post-hoc tests rather than multiple t-tests to control family-wise error rates. Finally, consider method validation parameters including lower limit of quantification (LLOQ), coefficient of variation across the dynamic range, and recovery experiments to assess accuracy.
Experimental designs for signaling pathway research using CDS2 Antibody, HRP conjugated should leverage its specificity and direct HRP conjugation advantages. Time-course experiments are particularly valuable—stimulate cells with relevant signaling molecules and collect samples at multiple time points to track CDS2 involvement in phospholipid biosynthesis and signal transduction pathways . Dose-response studies using pathway activators or inhibitors, followed by CDS2 protein detection, can establish quantitative relationships between pathway activation and CDS2 expression or modification. Co-immunoprecipitation studies can identify protein interaction partners, though these require careful optimization since the HRP conjugation may affect protein-protein interactions. Cell fractionation experiments followed by CDS2 detection in different cellular compartments can reveal translocation events during signaling. siRNA knockdown or CRISPR-Cas9 genome editing of CDS2, coupled with rescue experiments using wild-type or mutant constructs, provides functional validation of CDS2's role in specific pathways. Pharmacological inhibition studies targeting upstream or downstream pathway components with detection of CDS2 can position it within signaling cascades. Additionally, comparative analyses across multiple cell types can reveal tissue-specific variations in CDS2-dependent signaling. For all these approaches, the direct HRP conjugation eliminates secondary antibody cross-reactivity concerns and streamlines detection protocols, particularly valuable in multi-parameter studies. Multiplexing with phospho-specific antibodies against known signaling components can provide comprehensive pathway activation profiles when the experimental system permits sequential or parallel detection methods.
The phospholipid microenvironment significantly impacts CDS2 protein detection using HRP-conjugated antibodies through multiple mechanisms affecting both antigen accessibility and antibody-antigen interactions. CDS2 functions as phosphatidate cytidylyltransferase, an integral membrane protein involved in phospholipid biosynthesis, meaning its conformational state and epitope exposure are directly influenced by the surrounding lipid composition . Membrane solubilization conditions during sample preparation critically affect detection—mild detergents (0.1-0.5% Triton X-100 or CHAPS) preserve native protein conformation better than harsh detergents like SDS, potentially maintaining conformational epitopes recognized by the polyclonal antibody. The antibody targets amino acids 354-445 of human CDS2 , a region that may be partially embedded in or associated with membrane structures, making complete solubilization essential for epitope accessibility. Lipid rafts and microdomains can sequester CDS2 and affect detergent extraction efficiency, potentially leading to underestimation of protein levels. For fixed tissue samples, lipid-rich environments may require specialized antigen retrieval techniques beyond standard methods, such as lipid extraction steps or extended retrieval times. Phospholipid-protein interactions may mask epitopes recognized by the antibody, particularly if the target region participates in substrate binding. Furthermore, post-translational modifications of CDS2 may be regulated by the phospholipid environment, potentially affecting antibody recognition if these modifications alter the target epitope structure. Researchers should consider membrane fraction enrichment procedures and compare multiple extraction methods when working with this membrane-associated enzyme to ensure comprehensive and representative detection.
