Description

Biotin-LC-LC-NHS is a biotinylation reagent featuring an N-hydroxysuccinimide (NHS) group that activates carboxylic acid groups on biotin, enabling efficient coupling reactions. With a 30.5 Å spacer, it minimizes steric hindrance during conjugation processes [1]. This reagent has been successfully employed to biotinylate small molecules like paclitaxel (Item No. 10461) and coenzyme Q10 (Item No. 11506), facilitating their characterization for binding site studies [1, 2].
