BIOTIN-NHS Structural

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.

Chemical properties

White Solid

The Uses of BIOTIN-NHS

Biotin-NHS is used in the biotinylation of proteins and peptides. Couples with primary amine in the pH range 6.5-8.5.

The Uses of BIOTIN-NHS

Amino reactive biotin reagent for preparing biotinylated surfaces or polypeptides.

The Uses of BIOTIN-NHS

amine reactive biotinylation reagent

Purification Methods

Recrystallise the ester from refluxing isoPrOH and dry it in a vacuum over P2O5 + KOH. [Jasiewicz et al. Exp Cell Biol 100 213 1976.]
