Properties

Description

This extended amine-reactive crosslinker connects a pyridyldithio (SPDP) group to an N-hydroxysuccinimide (NHS) ester via an ultra-long polyethylene glycol (PEG36) chain. The SPDP group enables exchange with thiols to form reversible disulfide linkages. The NHS ester targets primary amines. The PEG36 chain provides exceptional aqueous solubility and spatial flexibility.
