Carboxyl reactive biotinylation reagents, EZ-Link™

Carboxyl reactive biotinylation reagents, EZ-Link™

Supplier: Thermo Fisher Scientific

Carboxyl groups, in the form of carboxy termini, aspartate residues or glutamate residues, can be targeted for biotin labeling using amine-derivatised biotin molecules. This reaction is mediated by a class of crosslinkers known as carbodiimides and results in the formation of an amide bond. The reaction with EDC, the most common carbodiimide crosslinker, is generally performed in an MES buffer at pH 4,5 to 5 and requires just minutes to complete.
