Properties

Description

This heterobifunctional linker features a 2-pyridyldithio handle and a terminal propargyl alkyne connected by a tetraethylene glycol (PEG4) spacer. The 2-pyridyldithio group undergoes thiol-disulfide exchange with free sulfhydryls to form reversible disulfide bonds. The propargyl group participates in copper-catalyzed click chemistry with azides. The PEG4 spacer maintains aqueous compatibility.
