Biotinylation of antibodies

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 ... WebJan 10, 2024 · 3.1 Biotinylation of Antibodies. The most common approach to biotin-label antibodies is to use N-hydroxysuccinimide (NHS) esters. At pH 7–9, NHS-biotin esters will react specifically with the primary amines in lysine side chains and the N-terminus, creating a stable amide bond. However, the number of biotins incorporated per antibody should ...
