What is BIOTIN-NHS?

Description

N-Hydroxysuccinimide (NHS) activates carboxylic acid groups (on biotin) to facilitate coupling reactions. Biotin-NHS is a compound used to attach biotin to primary amines under alkaline conditions (pH~8-9). For example, lysines on the surface of proteins, including antibodies, are ideal targets for biotinylation with this compound.
