The ImmunoProbe™ biotinylation kit produced by Sigma, USA (BK-101) is based on the use of biotin-amidocaproate- N -hydroxysulfo-succinimide ester (BAC-sulfo-NHS).
Proteins can be biotinylated chemically or enzymatically. Chemical biotinylation utilises various conjugation chemistries to yield nonspecific biotinylation of amines, carboxylates, sulfhydryls and carbohydrates (e.g., NHS-coupling gives biotinylation of any primary amines in the protein). Enzymatic biotinylation results in biotinylation of a specific lysine within a certain sequence by a bacterial biotin ligase. Most chemical biotinylation reagents consist of a reactive group attached …
