In the specialized field of molecular biology and protein analysis, the use of high-quality reagents is paramount for obtaining reliable experimental data. My experie MAGEA3 blocking peptide-NP_005353 nce with various laboratory tool STEA3 Blocking Peptide - AF0652-BP s has highlighted the critical importance of selecting the right controls. Among these, the 323 a3 blocking peptide serves as a vital component for researchers working with specific monoclonal antibody clones.
Defining the 323 a3 Blocking Peptide
When discussing the 323 a3 blocking peptide, it is essential to understand its primary function. A blocking peptide is specifically designed to be used with its corresponding antibody to con EpCAM / CD326 (Epithelial Marker) Antibodyderived from MCF-7 human breast cancer cells. Clone: 323/A3. Gene ID: 4072. firm specificity. Essentially, these are peptides that bind specifically to the target antibody and block antibody binding, effectively acting as a negative control. By pre-incubating the antibody with this peptide, researchers can verify that t Monoclonal Anti-CD326 antibody produced in mouse he signal observed in an assay is indeed specific to the target protein rather than the result of non-specific binding.
Contextualizing the 323/A3 Clone
The "323" and "A3" nomenclature typically refers to a well-characterized mouse monoclonal [323/A3] antibody. This specific clone is widely recognized for its utility in targeting markers like EpCAM (CD32 Abcepta provides over 30000 primary antibodiesof the highest quality for your research. Our scientists now manufacture over 4000 antibodies per year! 6). Ep-CAM functions as a homotypic calcium-independent cell adhesion molecule, which is why the EpCAM antibody [323/A3] is a staple in many laboratories.
When sourcing these materials, I have noted that reputable suppliers like Abcepta provides over 30000 primary antibodies, ensuring that the 323/A3 antibody is available in various formats, including conjugated versions for flow cytometry or standard Western Blotting (where the MW is often observed around 35 kDa).
Practical Application and Experimental Design
In my own research workflows, I often rely on the fact that blocking peptides can be used as controls to identify non-specific binding of antibodies. Whether I am investigating the EpCAM / CD326 (Epithelial Marker) Antibody or exploring other targets like the CALHM3 Blocking Peptide (#BLP-CC323), the principle remains the same: the peptide is the original antigen used for immunization during the antibody generation process.

* Quality Assurance: Using a peptide that is designed to be used with its corresponding antibody helps in distinguishing true signals from background noise.
* Versatility: While some researchers focus on the A3 peptide components, others may compare them to different standards, such as the Ovalbumin protein Ova (323-339), which is frequently used in immunology research.
Considerations for Procurement
When you decide to buy KLC3 Blocking Peptide 33R-5120 or similar specialized reage MW, 35 kDa. NCBI Number, 4072. Additional Information, For laboratory research only, not for drug, diagnostic or other use. Application, FC, ICC, IF, IHC, Read more nts, always ensure they are validated for your specific application. The 323/A3 clone is a classic example of a mouse monoclonal antibody detecting EpCAM, and its reliability is well-documented in scientific literature. Whether you are performing IHC, ICC, or Western Blot, having the correct blocking peptide on hand is a best practice that preserves the integrity of your experimental results.
By adhering to these protocols and utilizing the appropriate blocking peptides, researchers can confidently navigate their data, knowing that their findings are grounded in verified, specific molecular interactions. Always refer to the specific datasheet provided by your supplier to confirm that the peptide is the exact match for your antibody clone.
