Sulpho-SANPAH (Sulphosuccinimidyl-6-(4′-azido-2′-nitrophenylamino)hexanoate), Sigma-Aldrich®

Catalog Number: (SIAL803332-50MG)
Supplier: Merck
Description: ANB-NOS and Sulfo-SANPAH are heterobifunctional crosslinkers that contain an amine-reactive N-hydroxysuccinimide (NHS) ester and a photoactivatable nitrophenyl azide. NHS esters react efficiently with primary amino groups (-NH2) in pH 7-9 buffers to form stable amide bonds. When exposed to UV light nitrophenyl azides form a nitrene group that can initiate addition reactions with double bonds, insertion into C-H and N-H sites, or subsequent ring expansion to react with a nucleophile (e.g., primary amines).
