Sulfo-SANPAH(CAT: M009185) (N-Sulfosuccinimidyl 6-(4′-azido-2′-nitrophenylamino) hexanoate) is a heterobifunctional, photoactivatable crosslinker widely used in bioconjugation and surface functionalization applications. It contains an NHS ester group that reacts with primary amines and a photo-reactive aryl azide group that forms covalent bonds with aliphatic or aromatic carbon groups upon UV activation. Sulfo-SANPAH is highly water-soluble, making it ideal for aqueous protein immobilization without the need for organic solvents. It is commonly used to attach extracellular matrix proteins to hydrogels, tissue culture surfaces, or biomaterials, facilitating cell adhesion and biointerface engineering in tissue engineering and cell biology research.
