Biotinylation of antibodies
WebThe ideal countermeasures for BoNT exposure are monoclonal antibodies or BoNT antisera, which form BoNT-containing immune complexes that are rapidly cleared from the general circulation. Clearance of opsonized toxins may involve complement receptor-mediated immunoadherence to red blood cells (RBC) in primates or to platelets in rodents. WebJan 2, 2024 · Labeling antibodies with biotin (biotinylation) is a useful and simple technique. Biotin's small size (244 Da) usually has little effect on the biological activity of the protein target. The most common way to biotinylate an antibody is to cross-link a biotin succinimidyl ester to a primary amine. There are many commercially available types of ...
