Biotin-PEG4-NHS

Biotin-PEG4-NHS is an amine reactive reagent that contains biotin linked via a four-unit PEG spacer to N-hydroxysuccinimide (NHS), which facilitates the coupling of biotin to primary amines. Biotin-PEG4-NHS has been used in the biotinylation of proteins and antibodies.Formal Name: 21-[(3aS,4S,6aR)-hexahydro-2-oxo-1H-thieno[3,4-d]imidazol-4-yl]-17-oxo-4,7,10,13-tetraoxa-16-azaheneicosanoic acid, 2,5-dioxo-1-pyrrolidinyl ester.
