Biotinylation - Wikipedia

In biochemistry, biotinylation is the process of covalently attaching biotin to a protein, nucleic acid or other molecule. Biotinylation is rapid, specific and is unlikely to disturb the natural function of the molecule due to the small size of biotin (MW = 244.31 g/mol). Biotin binds to streptavidin and avidin with an … See more Proteins can be biotinylated chemically or enzymatically. Chemical biotinylation utilises various conjugation chemistries to yield nonspecific biotinylation of amines, carboxylates, sulfhydryls and carbohydrates … See more The non-covalent bond formed between biotin and avidin or streptavidin has a binding affinity that is higher than most antigen and antibody bonds and approaches the … See more • Hermanson, G.T.
