Properties

Description

This heterobifunctional reagent contains a free thiol group and a carboxylic acid separated by a short PEG2 spacer. The thiol group reacts selectively with maleimides, haloacetamides, or gold surfaces. The carboxylic acid group enables coupling with primary amines via standard carbodiimide activation. The PEG2 backbone provides water solubility and compact separation.
