ANB-NOS Crosslinker, also known as N-5-Azido-2-nitrobenzoyloxysuccinimide, is a heterobifunctional protein crosslinker with a spacer arm length of 7.7 angstroms. The ANB-NOS crosslinking reagent contains an NHS ester that reacts with primary amines and a nitrophenylazide group that is photoreactive at 320-350 nm toward amino groups. ANB-NOS Crosslinker is useful for making ADCs (antibody drug conjugates).
