MCF2, also known as Proto-oncogene DBL or ARHGEF21, functions as a guanine nucleotide exchange factor (GEF) that modulates the Rho family of GTPases. It is particularly significant in research because it promotes the conversion of Rho family GTPases from GDP-bound to GTP-bound forms, acting as a molecular switch in signal transduction pathways . MCF2 plays a crucial role in the regulation of cell growth, proliferation, and migration, making it relevant to cancer research and studies of cytoskeletal dynamics . The different isoforms of MCF2 exhibit varying activities toward specific GTPases: isoform 1 shows no activity toward RHOA, RAC1 or CDC42; isoform 2 has decreased GEF activity toward CDC42; isoform 3 demonstrates weak but significant activity toward RAC1 and CDC42; while isoform 4 shows significant activity toward RHOA and CDC42 .
An HRP (Horseradish Peroxidase)-conjugated antibody is an immunological reagent where the antibody molecule is chemically linked to HRP enzyme. This conjugation enables detection by catalyzing a colorimetric, chemiluminescent, or fluorescent reaction when appropriate substrates are added . In experimental applications, the HRP-conjugated antibody binds specifically to its target antigen (in this case, MCF2 protein), and the attached HRP enzyme produces a detectable signal that corresponds to the presence and quantity of the target protein . This conjugation results from directional covalent bonding of HRP to the antibody, typically performed at near-neutral pH to ensure high conjugation efficiency and 100% antibody recovery . HRP-conjugated antibodies are particularly valuable in techniques like Western blotting and ELISA, where they can be used at dilutions ranging from 1:500 to 1:100,000 depending on the specific application and antibody sensitivity .
MCF2 protein functions as a guanine nucleotide exchange factor, regulating the activity of Rho family GTPases by facilitating the exchange of GDP for GTP. Structurally, the human MCF2 protein has a calculated molecular weight of approximately 108 kDa and contains specific functional domains that mediate its GEF activity . The protein sequence from amino acids 872-1001 (VKMTWLKEIRNILLKQQELLTVKKRKQQDQLTERDK-FQISLQQNDEKQQGAFISTEETEEHTSTVEVCAIASVQAEANTVWTEASQSAEISEEPAE-WSSNYFYPTYDENEEENRPLMRPVSEMALLY) represents one important region of the protein that is often used as an immunogen for antibody production . MCF2 is primarily localized in the cytoplasm and membrane of cells, where it interacts with its target GTPases . The oncogenic potential of MCF2 derives from its ability to activate Rho GTPases, which then modulate cytoskeletal dynamics, cell migration, and proliferation pathways implicated in cancer development and progression .
For optimal Western blot results with MCF2 Antibody, HRP conjugated, researchers should implement several key optimization strategies. First, determine the appropriate dilution range; while specific MCF2 antibodies may vary, HRP-conjugated antibodies typically perform well at dilutions between 1:500 and 1:2000 for Western blotting . Sample preparation is crucial – use fresh cell lysates when possible, and ensure complete protein denaturation in loading buffer containing SDS and a reducing agent . During electrophoresis, load adequate protein (20-50 μg of total protein per lane) to detect MCF2, which has an observed molecular weight of 108 kDa . For transfer, use PVDF membranes for optimal protein binding and signal retention with HRP-conjugated antibodies . Blocking should be performed using 5% non-fat dry milk or BSA in TBST for at least 1 hour at room temperature to minimize background . After primary antibody incubation, perform stringent washing steps (at least 3×10 minutes with TBST) before detection with an appropriate chemiluminescent substrate optimized for HRP . For troubleshooting, verify positive control samples (such as HT-29 cells, which are known to express MCF2) and consider titrating the antibody concentration if signal-to-noise ratios are suboptimal.
When designing ELISA protocols with MCF2 Antibody, HRP conjugated, researchers should address several key considerations to ensure reliable and reproducible results. First, coating concentration and conditions must be optimized – typically using purified MCF2 protein or peptide at 1-10 μg/ml in carbonate/bicarbonate buffer (pH 9.6) overnight at 4°C . Blocking requires careful selection of blocking reagents compatible with HRP detection systems; 1-5% BSA in PBS is often effective while avoiding milk proteins which can sometimes interfere with phospho-specific antibodies . For antibody dilution, MCF2 Antibody, HRP conjugated should be tested in a range from 1:500 to 1:2000, with titration experiments to determine optimal concentration for maximizing specific signal while minimizing background . The substrate selection is critical for HRP-conjugated antibodies – TMB (3,3',5,5'-tetramethylbenzidine) provides sensitive colorimetric detection, while luminol-based substrates offer enhanced sensitivity for chemiluminescent detection . Include appropriate positive controls (recombinant MCF2 protein) and negative controls (irrelevant proteins of similar molecular weight) . For quantitative ELISAs, prepare a standard curve using purified recombinant MCF2 protein at concentrations ranging from 0-1000 ng/ml. Finally, ensure that detection conditions (temperature, development time, stopping procedure) are standardized across all experimental replicates.
Validating the specificity of MCF2 Antibody, HRP conjugated requires a multi-faceted approach using complementary techniques. Begin with positive control samples known to express MCF2, such as HT-29 cells, which serve as a benchmark for antibody performance . Perform a side-by-side comparison with multiple MCF2 antibodies from different suppliers or those recognizing different epitopes to confirm consistent detection patterns . Include a pre-absorption test where the antibody is pre-incubated with excess immunizing peptide before application to samples; specific staining should be significantly reduced or eliminated . For definitive validation, use genetic models such as MCF2 knockout cell lines created via CRISPR-Cas9 or cells treated with MCF2-specific siRNA; a specific antibody will show reduced or absent signal in these samples compared to wild-type controls . Cross-reactivity assessment should be performed using closely related proteins (other GEF family members) to confirm the antibody does not detect these proteins at the expected molecular weight of MCF2 (108 kDa) . Finally, confirm cellular localization patterns using immunocytochemistry, which should show the expected cytoplasmic and membrane localization consistent with MCF2's known distribution . This comprehensive validation strategy ensures that experimental findings accurately reflect MCF2 biology rather than non-specific interactions.
MCF2 Antibody, HRP conjugated offers powerful capabilities for dissecting MCF2's role in cancer signaling pathways through multiple sophisticated approaches.

For mechanistic studies, researchers can combine immunoprecipitation with MCF2 antibodies followed by Western blotting with HRP-conjugated antibodies against potential binding partners to map protein-protein interaction networks involving MCF2 . In situ applications such as immunohistochemistry or immunofluorescence with adapted protocols can visualize MCF2 localization changes during oncogenic transformation or in response to targeted therapies . To integrate MCF2 into broader signaling networks, the antibody can be used in high-throughput phosphoproteomic analyses after MCF2 modulation through overexpression, knockdown, or inhibition of its GEF activity, revealing downstream effectors regulated by MCF2-mediated Rho GTPase activation . These approaches collectively provide a comprehensive view of how MCF2 contributes to cancer hallmarks like migration, invasion, and proliferation.
Studying the differential activity of MCF2 isoforms requires sophisticated experimental strategies that leverage the specificity of HRP-conjugated antibodies. Researchers should first develop isoform-specific detection methods by designing immunogens from unique regions of each isoform (1, 2, 3, and 4) to generate antibodies with isoform selectivity . Western blot analysis can then differentiate between isoforms based on slight molecular weight differences and expression patterns across cell types and tissues . For functional studies, combine selective knockdown of individual isoforms using siRNA or CRISPR-Cas9 with Western blot detection using HRP-conjugated MCF2 antibodies to confirm isoform-specific depletion and assess compensatory changes in other isoforms . To directly assess GEF activity, researchers can perform pull-down assays using GST-tagged RhoA, Rac1, or Cdc42 loaded with GDP, followed by nucleotide exchange rate measurement in the presence of immunoprecipitated MCF2 isoforms . The differential activation of downstream effectors can be monitored using HRP-conjugated antibodies against phosphorylated forms of targets like PAK, ROCK, or mDia following selective expression or inhibition of specific MCF2 isoforms . Importantly, researchers can correlate isoform expression with functional outcomes by transfecting cells with isoform-specific expression constructs and measuring parameters such as stress fiber formation, membrane ruffling, or filopodia extension – each associated with different Rho GTPase activities that are differentially regulated by MCF2 isoforms 1-4 .
Investigating the relationship between MCF2 and Rho family GTPases requires sophisticated biochemical and cellular approaches utilizing HRP-conjugated antibodies. Researchers can implement active GTPase pull-down assays where GST-tagged GTPase-binding domains (such as rhotekin-RBD for RhoA or PAK-PBD for Rac1/Cdc42) are used to selectively capture GTP-bound (active) GTPases, followed by Western blot detection with HRP-conjugated antibodies specific to individual Rho GTPases . This approach can quantitatively assess how MCF2 modulation affects GTPase activation states. Co-immunoprecipitation experiments using MCF2 antibodies followed by Western blotting with HRP-conjugated antibodies against RHOA, RAC1, and CDC42 can reveal direct physical interactions and complex formation between MCF2 and its target GTPases . For spatiotemporal analysis, researchers can perform subcellular fractionation experiments followed by Western blotting with HRP-conjugated antibodies to determine the compartmentalization of MCF2 and Rho GTPases (membrane versus cytosolic pools) under various stimulation conditions . Structure-function studies can be conducted by expressing truncated or point-mutated MCF2 constructs, followed by assessment of their impact on Rho GTPase activation using HRP-conjugated antibodies in Western blot analyses . Additionally, researchers can apply inhibitors of specific GTPase signaling pathways, then use MCF2 Antibody, HRP conjugated to determine feedback effects on MCF2 expression, localization, or post-translational modifications, revealing bidirectional regulation between MCF2 and its target GTPases .
Optimal buffer conditions and storage parameters are critical for maintaining the stability and performance of MCF2 Antibody, HRP conjugated. The recommended storage buffer composition includes PBS with 50% glycerol, 0.03-0.05% Proclin 300 as a preservative, and approximately 0.5-1% BSA at pH 7.4 . This formulation provides protein stability while preventing microbial growth. For long-term storage, the antibody should be kept at -20°C or -80°C, with -20°C being adequate for most applications . Researchers should aliquot the antibody upon receipt to minimize freeze-thaw cycles, as repeated freezing and thawing significantly reduces HRP enzymatic activity and antibody binding capacity . Working dilutions should be prepared fresh in appropriate buffers (typically TBST with 1-5% BSA for Western blotting applications) and used within 24 hours . When handling the antibody, exposure to light should be minimized as HRP conjugates are light-sensitive, particularly when diluted . For applications requiring high sensitivity, antioxidants like sodium azide must be strictly avoided as they irreversibly inhibit HRP activity . Temperature transitions should be gradual, allowing frozen antibodies to thaw completely at 4°C before handling to prevent protein denaturation . Following these storage and handling guidelines ensures maximum retention of both antibody specificity and HRP enzymatic activity, critical for sensitive detection of MCF2 protein.
The conjugation process linking HRP to MCF2 antibodies introduces several factors that can influence antibody performance, requiring specific quality control measures. The conjugation chemistry involves directional covalent bonding of HRP to the antibody using proprietary reagents, which can impact the antibody's antigen-binding capacity if conjugation occurs near the antigen-binding site . The antibody-to-HRP ratio is critical; optimal molar ratios between 1:4 and 1:1 (antibody:HRP) balance detection sensitivity with potential steric hindrance . To ensure consistency, researchers should implement multiple quality control measures: (1) Perform a validation Western blot using positive control samples known to express MCF2 (e.g., HT-29 cells) to confirm specific detection at the expected molecular weight (108 kDa) ; (2) Include a titration series in each new experimental batch to verify consistent performance across antibody lots ; (3) Compare signal intensity with unconjugated primary antibody plus HRP-secondary antibody detection to assess whether direct conjugation affects sensitivity ; (4) Evaluate background signal levels using negative control samples (MCF2-negative cell lines or tissues) to confirm specificity is maintained after conjugation ; (5) Assess antibody functional stability by comparing signal intensity of freshly thawed aliquots versus those stored at 4°C for different time periods to establish working solution stability parameters ; and (6) Document lot-to-lot variation by maintaining reference samples tested with each new antibody lot . These comprehensive quality control measures ensure reliable, reproducible results when using MCF2 Antibody, HRP conjugated in research applications.
When encountering weak or absent signals with MCF2 Antibody, HRP conjugated, researchers should implement a systematic troubleshooting approach. First, verify MCF2 expression in your sample using a positive control like HT-29 cells, which are known to express MCF2 . If the control also shows weak signal, check antibody activity by performing a dot blot with recombinant MCF2 protein at various concentrations to confirm HRP functionality . Inadequate protein loading often causes weak signals; increase loading amount to 30-50 μg of total protein per lane and verify with a protein loading control . Improper transfer can significantly impact results; optimize transfer conditions by using fresh transfer buffer, ensuring adequate contact between gel and membrane, and considering longer transfer times for the relatively large MCF2 protein (108 kDa) . Insufficient blocking leads to high background masking specific signals; extend blocking time to 1-2 hours using 5% BSA in TBST rather than milk-based blockers, which can sometimes interfere with phospho-epitope detection . Antibody concentration is critical; try more concentrated antibody dilutions (1:250 to 1:500) if signal is weak . Detection system sensitivity matters; switch to more sensitive chemiluminescent substrates specifically formulated for HRP or extend exposure times when using imaging systems . Buffer composition issues can inhibit HRP activity; ensure sodium azide (an HRP inhibitor) is not present in any buffers used during antibody incubation . Finally, consider protein modifications or isoform expression patterns that might affect epitope availability; try denaturing conditions that fully expose linear epitopes or alternative lysis methods that better preserve protein conformation .
Addressing high background issues with MCF2 Antibody, HRP conjugated requires a multi-faceted approach targeting each potential source of non-specific signal. Begin by optimizing blocking conditions; increase blocking time to 2 hours at room temperature using fresh 5% BSA or 5% non-fat dry milk in TBST, ensuring complete coverage of the membrane . The antibody dilution factor significantly impacts background; use more dilute antibody preparations (1:2000 to 1:5000) while extending incubation time to maintain specific signal detection . Washing protocols are crucial; implement more stringent washing with increased duration (4-5 washes of 10 minutes each) and higher detergent concentration (0.1-0.2% Tween-20) in wash buffers . Secondary reagent issues can be eliminated since the direct HRP conjugation eliminates secondary antibody cross-reactivity, a significant advantage of conjugated antibodies . Membrane quality impacts background; use fresh, high-quality PVDF or nitrocellulose membranes and handle only with clean forceps to prevent protein contamination . Detection system optimization involves using substrate solutions with lower hydrogen peroxide concentration to reduce non-specific HRP activation, and precisely timing the development process to achieve optimal signal-to-noise ratio . Sample preparation quality is critical; ensure thorough centrifugation of lysates to remove particulates that can cause spotty background and include reducing agents in sample buffers to minimize protein aggregation . Environmental contamination can be prevented by preparing all solutions with ultrapure water and maintaining clean laboratory surfaces and equipment . Implementing this comprehensive troubleshooting strategy systematically addresses the multiple potential sources of high background, resulting in cleaner Western blots and immunoassays with MCF2 Antibody, HRP conjugated.

Subcellular fractionation can isolate cytoplasmic and membrane fractions where MCF2 is predominantly located, effectively concentrating the protein and reducing sample complexity . Enhanced lysis protocols using buffer systems containing 1% NP-40 or Triton X-100 with protease and phosphatase inhibitors ensure complete extraction of membrane-associated MCF2 protein . Signal amplification systems dramatically increase detection sensitivity; researchers should employ enhanced chemiluminescent substrates specifically formulated for ultrasensitive HRP detection, capable of detecting femtogram levels of protein . Membrane optimization also contributes to sensitivity; low-fluorescence PVDF membranes with 0.2 μm pore size improve protein retention and reduce background compared to standard membranes . Detection instrument settings can be optimized; when using digital imaging systems, longer exposure times combined with frame averaging can detect weaker signals while maintaining acceptable background levels . Sample handling modifications matter; reducing total protein per lane (15-20 μg) while increasing antibody concentration and incubation time (overnight at 4°C) can paradoxically improve signal-to-noise ratio for low-abundance proteins . Finally, downstream signal enhancement using tyramide signal amplification (TSA) compatible with HRP-conjugated antibodies can provide 10-100 fold signal enhancement through catalyzed reporter deposition . By combining these approaches, researchers can significantly improve detection of low-abundance MCF2 protein even in challenging biological samples.

Adapting protocols for studying MCF2 across different model systems and species requires careful consideration of several key factors. First, researchers must address species cross-reactivity; while the MCF2 Antibody, HRP conjugated from AFG Scientific shows specific reactivity with human samples, researchers working with other species should verify sequence homology between the immunogen (human MCF2 amino acids 705-925) and the target species' MCF2 protein . The Assay Genie antibody shows reactivity with both human and mouse samples, making it suitable for comparative studies . Expression level variations between model systems necessitate optimization; MCF2 may be expressed at different levels across cell lines, primary cultures, and tissues, requiring adjustment of antibody dilutions (more concentrated for lower-expressing systems, more dilute for high-expressing systems) . Sample preparation protocols must be species-optimized; for example, mouse tissues may require different lysis buffers than human cell lines to effectively extract MCF2 while preserving its epitopes . Detection system sensitivity should match the experimental model; less abundant MCF2 in certain systems may require more sensitive chemiluminescent substrates or signal amplification methods . Control selection is critical; researchers should identify appropriate positive control samples for each species (e.g., HT-29 cells for human studies) and include species-specific loading controls to normalize data across samples. For developmental studies, researchers should consider temporal expression patterns; MCF2 expression and isoform distribution may vary during development, requiring time-course analyses with age-matched controls . Additionally, genetic background effects in model organisms may influence MCF2 expression or function, necessitating consistent use of defined genetic backgrounds and appropriate wild-type controls . By systematically addressing these considerations, researchers can effectively study MCF2 across diverse experimental systems while maintaining scientific rigor.
Simultaneous detection of MCF2 and its interacting partners or downstream effectors requires sophisticated technical approaches that preserve complex formation while enabling specific detection.
