Properties

Description

This long-chain heterobifunctional crosslinker links a pyridyldithio (SPDP) group to a carboxylic acid terminal via an extended polyethylene glycol (PEG24) spacer. The SPDP handle reacts with thiols to form reversible disulfide bonds. The carboxylic acid terminal couples to amines via amidation. The PEG24 chain offers high water solubility and spatial reach.
