Properties

Description

This product is a long monodisperse polyethylene glycol (PEG) linker terminated with a pyridyldithiol (SPDP) group and a carboxylic acid functionality. The extended PEG chain provides superior water solubility and suppresses steric hindrance during bioconjugation steps. The disulfide motif enables reversible thiol exchange under reducing conditions.
