| Description | N-Hydroxysuccinimide (NHS) activates carboxylic acid groups to aid coupling reactions. Biotin-X-NHS attaches biotin to primary amines under alkaline conditions (pH ~ 8-9). It targets lysines on protein surfaces, such as antibodies. Biotin-X-NHS includes a six-atom spacer arm, minimizing steric effects compared to Biotin-NHS (Item No. 13315). |
