What is the At5g39480 antibody and what protein does it target in Arabidopsis thaliana?

The At5g39480 antibody (product code CSB-PA861844XA01DOA) is a research reagent designed to specifically recognize and bind to the protein encoded by the At5g39480 gene in Arabidopsis thaliana, commonly known as mouse-ear cress . This antibody binds directly to its target protein via the variable antibody region that recognizes specific epitopes on the At5g39480 protein . The target protein is associated with biological processes in Arabidopsis thaliana, which serves as an important model organism in plant molecular biology. Researchers typically use this antibody in various applications including western blotting, immunohistochemistry, and other immunodetection methods to study the expression, localization, and function of the At5g39480 protein. Understanding the fundamental properties of this antibody is essential for designing well-controlled experiments and accurately interpreting research data.

What are the key differences in reactivity between At5g39480 antibody and other Arabidopsis protein antibodies?

The At5g39480 antibody exhibits specific reactivity patterns that distinguish it from other Arabidopsis protein antibodies based on epitope recognition and cross-reactivity profiles. While the At5g39480 antibody is designed to target the specific protein encoded by the At5g39480 gene, its reactivity should be carefully compared with antibodies targeting related proteins such as At1g53310 (PEPC 1) and At3g14940 (PEPC 3) . Drawing from examples like the PEPC antibody (AS09 458), which was developed using KLH-conjugated synthetic peptides conserved across different plant species, properly designed At5g39480 antibodies should demonstrate minimal cross-reactivity with non-target proteins . Researchers should note that reactivity patterns can vary significantly between different plant species, as evident in studies with antibodies like anti-PEPC, which shows different reactivity in Arabidopsis thaliana, Spinacia oleracea, Hordeum vulgare, and Zea mays . Unlike some broadly reactive antibodies, At5g39480 antibodies may have more restricted species reactivity, potentially limited to Arabidopsis thaliana and closely related species, so careful validation in your specific experimental system is essential before proceeding with comprehensive studies.

What is the optimal protein extraction method for At5g39480 detection in Arabidopsis tissues?

The optimal protein extraction method for At5g39480 detection requires careful consideration of tissue type, protein stability, and potential interfering compounds in Arabidopsis samples. Based on successful protocols with plant proteins like PEPC, which is particularly prone to proteolysis, extraction buffers containing protease inhibitors are essential for preserving protein integrity during the extraction process . For At5g39480 antibody applications, a recommended approach involves using a Protein Extraction Buffer (similar to PEB, AS08 300) supplemented with chymotrypsin and commercial protease inhibitor cocktails to prevent degradation during sample preparation . The extraction process should include tissue disruption in cold buffer (typically containing 1 M Tris-HCl, pH 6.8, 10% SDS, 15% sucrose, and 0.5 DTT), followed by centrifugation to remove cellular debris . Temperature control is crucial throughout the extraction process, with sample denaturation recommended at moderate temperatures (approximately 75°C for 5 minutes) rather than boiling, which can cause protein aggregation or degradation in plant samples . Different Arabidopsis tissues (leaves, roots, flowers) may require slight modifications to the extraction protocol, with senescent versus non-senescent tissues potentially requiring different handling due to varying levels of proteolytic enzymes and secondary metabolites that could interfere with antibody binding.

How should I optimize western blot protocols specifically for At5g39480 antibody?

Optimizing western blot protocols for At5g39480 antibody requires careful attention to several critical parameters to achieve specific and sensitive detection. For protein separation, 4-12% gradient gels (such as NuPage LDS-PAGE systems) provide excellent resolution for plant proteins in the expected molecular weight range of At5g39480 . The transfer step should be conducted for approximately 1 hour to PVDF membranes, which generally offer better protein retention and lower background than nitrocellulose for plant proteins . Following transfer, immediate blocking with 2% blocking reagent in TBS-T (20 mM Tris, 137 mM sodium chloride pH 7.6 with 0.1% Tween-20) for 1 hour at room temperature with agitation is recommended to minimize non-specific binding . The optimal primary antibody dilution should be determined through titration experiments, starting with a range of 1:1,000 to 1:10,000, with incubation for 1 hour at room temperature with agitation . After washing steps (two brief rinses, one 15-minute wash, and three 5-minute washes in TBS-T), the secondary antibody (anti-rabbit IgG HRP-conjugated) should be used at dilutions between 1:10,000 and 1:50,000 in 2% blocking solution for 1 hour at room temperature . Development with chemiluminescent detection reagents for approximately 5 minutes, followed by image capture using a CCD imager or equivalent system, completes the protocol . Including appropriate positive controls and loading 5-10 μg of total protein per lane typically provides good signal while minimizing background.

What controls are essential when using At5g39480 antibody in immunolocalization studies?

Implementing rigorous controls in immunolocalization studies with At5g39480 antibody is fundamental for generating reliable and interpretable results. Primary negative controls should include omission of the primary antibody while maintaining all other conditions, which helps identify non-specific binding of the secondary antibody to plant tissues . Peptide competition assays, where the primary antibody is pre-incubated with the immunizing peptide before application to the tissue, serve as specificity controls that should eliminate specific staining if the antibody is truly binding to its intended target . Genetic controls using Arabidopsis thaliana knockout/knockdown lines for the At5g39480 gene represent the gold standard negative control, as these should show significantly reduced or absent signal compared to wild-type plants, directly confirming antibody specificity . Positive controls should include tissues known to express the target protein at high levels, with recommended dilutions starting at 1:500 for immunolocalization applications . Additional methodological controls include testing different fixation methods (paraformaldehyde versus glutaraldehyde) and antigen retrieval techniques, as plant cell walls and vacuoles can present unique challenges for antibody penetration and epitope accessibility . Cross-validation using multiple detection methods, such as combining immunofluorescence with in situ hybridization or reporter gene expression, further strengthens the confidence in immunolocalization results and helps distinguish between specific signal and artifacts that may arise during processing.

How can I address weak or absent signal when using At5g39480 antibody in western blots?

When encountering weak or absent signals with At5g39480 antibody in western blots, a systematic troubleshooting approach is essential for resolving the issue. First, examine your protein extraction protocol as inadequate extraction or protein degradation frequently causes signal problems; plant proteins are particularly susceptible to proteolysis, so ensure your extraction buffer contains appropriate protease inhibitors and consider adding chymotrypsin specifically for Arabidopsis samples . Increase the amount of loaded protein incrementally from 5 μg to 20 μg per lane, as the target protein may be expressed at low levels or in specific developmental stages only . Optimize antibody concentration by testing a range of dilutions (from 1:500 to 1:10,000) to find the optimal balance between specific signal and background . Extending primary antibody incubation time from 1 hour to overnight at 4°C can sometimes improve detection of low-abundance targets without significantly increasing background . Consider using enhanced chemiluminescent substrates with higher sensitivity or switching to fluorescent secondary antibodies with direct scanning, which often provides better results for challenging targets . If these approaches fail, test alternative membrane types (PVDF versus nitrocellulose) and different blocking reagents (BSA versus commercial blocking solutions), as some target proteins and antibodies perform better with specific combinations . Finally, verify the expression pattern of At5g39480 in your specific tissue/condition using transcriptomic data, as the protein might not be expressed in sufficient quantities in your experimental system.

What strategies can reduce non-specific binding and background when using At5g39480 antibody?

Reducing non-specific binding and background when using At5g39480 antibody requires implementation of multiple optimization strategies throughout the experimental protocol. Begin by thoroughly validating your blocking solution, testing different concentrations (2-5%) and types (BSA, non-fat milk, commercial blockers) to identify the optimal formulation that minimizes background without compromising specific signal . Increase the number and duration of washing steps between antibody incubations, implementing a regimen of at least five washes (one 15-minute wash followed by four 5-minute washes) with TBS-T to remove unbound antibody effectively . Dilute both primary and secondary antibodies in fresh blocking solution rather than buffer alone, which helps reduce non-specific interactions; for At5g39480 antibody, start with higher dilutions (1:5,000 to 1:10,000) and adjust based on results . Pre-adsorb the antibody against plant material from a species that doesn't express the target (or from Arabidopsis knockout lines if available) to remove antibodies that may cross-react with other plant proteins . Consider adding 0.1-0.5% Triton X-100 or 0.05% Tween-20 to your antibody dilution buffers to reduce hydrophobic interactions that contribute to background . For particularly challenging samples with high background, implement a dual blocking strategy by first blocking with 2% BSA followed by 2% normal serum from the same species as your secondary antibody . Finally, ensure your secondary antibody is highly cross-adsorbed against plant proteins and used at appropriate dilutions (1:20,000 to 1:50,000) to minimize non-specific binding to plant tissues .

How should I troubleshoot inconsistent results between different batches of At5g39480 antibody?

Addressing inconsistent results between different antibody batches requires a combination of standardization procedures and careful experimental design. First, implement a comprehensive antibody validation protocol for each new batch, involving side-by-side testing with previous lots using identical samples and protocols to directly compare performance characteristics . Establish internal reference standards consisting of well-characterized Arabidopsis thaliana lysates that can be used across experiments to normalize signals and account for batch-to-batch variations . When possible, switch to recombinant monoclonal antibodies, which offer significantly reduced batch-to-batch variation compared to traditional polyclonal antibodies due to their production using defined antibody-encoding sequences . Maintain detailed records of antibody performance for each batch, including optimal dilutions, signal-to-noise ratios, and detection limits, allowing for protocol adjustments when switching between lots . Consider performing antibody titration experiments with each new batch to determine the optimal working concentration for your specific application rather than relying on previously established dilutions . Implement quantitative western blotting techniques using standard curves to enable more precise comparison between experiments conducted with different antibody batches . For critical experiments with high reproducibility requirements, purchase sufficient quantities of a single antibody batch to complete the entire research project, storing aliquots at -20°C to maintain stability and avoid repeated freeze-thaw cycles . Finally, incorporate positive control samples with known target expression levels in every experiment to provide consistent reference points for normalizing results across different antibody batches and experimental conditions.

How can At5g39480 antibody be used in co-immunoprecipitation studies to identify protein interaction partners?

Co-immunoprecipitation (Co-IP) with At5g39480 antibody enables the identification of protein interaction partners through a carefully optimized protocol suited for plant samples. Begin by extracting proteins under non-denaturing conditions using mild lysis buffers (typically containing 50 mM Tris-HCl pH 7.5, 150 mM NaCl, 1% NP-40 or 0.5% Triton X-100, and protease inhibitors) that preserve protein-protein interactions while efficiently releasing proteins from plant tissues . Pre-clear the lysate by incubation with protein A/G beads alone to remove proteins that bind non-specifically to the beads, reducing background in the final analysis . For the immunoprecipitation step, optimize the amount of At5g39480 antibody (typically 2-5 μg per mg of total protein) and incubation conditions (4-16 hours at 4°C under gentle rotation) to efficiently capture the target protein complex without disrupting interactions . After antibody incubation, add protein A/G beads and continue incubation for 1-3 hours, followed by thorough washing with increasingly stringent buffers to remove non-specifically bound proteins while maintaining specific interactions . Elute the immunoprecipitated complexes using either low pH, high salt conditions, or SDS buffer, depending on downstream applications and the stability of the interactions being studied . For identification of interaction partners, analyze the immunoprecipitated samples using techniques such as mass spectrometry, western blotting with antibodies against suspected interaction partners, or silver staining followed by protein identification . Include appropriate controls in parallel experiments, such as immunoprecipitation with non-specific IgG and reciprocal Co-IPs using antibodies against suspected interaction partners to validate true interactions versus false positives .

Report effect sizes alongside p-values to indicate the magnitude of observed differences, and consider employing Bayesian statistical frameworks which can be particularly valuable for small sample sizes typical in specialized plant antibody studies .

How do I interpret contradictory results between antibody-based detection of At5g39480 and transcriptomic data?

Resolving contradictions between antibody-based protein detection and transcriptomic data requires systematic investigation of both biological and technical factors. First, recognize that protein-mRNA discrepancies are biologically plausible due to post-transcriptional regulation mechanisms, including differential translation efficiency, protein stability, and post-translational modifications that can cause protein levels to deviate significantly from mRNA abundance . Examine the temporal dynamics of expression, as time lags between transcription and translation can create apparent discrepancies when samples are collected at single time points; consider time-course experiments to capture the relationship between mRNA induction and subsequent protein accumulation . Investigate potential cell type-specific expression patterns, as bulk tissue measurements may mask important spatial heterogeneity where protein and mRNA are differentially expressed across cell types within the same tissue . Evaluate technical considerations in antibody-based detection, including epitope accessibility issues, where post-translational modifications or protein-protein interactions might mask the epitope recognized by the At5g39480 antibody without affecting mRNA detection . Assess antibody specificity using the validation approaches described previously, as cross-reactivity with related proteins could lead to detection of proteins other than the intended At5g39480 target . For transcriptomic data, examine primer or probe specificity (for qRT-PCR) or read mapping specificity (for RNA-seq) to ensure accurate quantification of the specific At5g39480 transcript rather than related gene family members . Consider employing orthogonal techniques such as selected reaction monitoring mass spectrometry for absolute protein quantification or RNA-protein correlation studies across multiple conditions to better understand the relationship between transcription and protein abundance for this specific gene . Finally, investigate biological hypotheses that could explain genuine discrepancies, such as condition-specific post-translational regulation, differential protein turnover rates, or potential regulatory functions of the mRNA itself independent of its protein product.
