Properties

Description

This homobifunctional crosslinker features two pyridyldithio (SPDP) handles connected by an undecaethylene glycol (PEG11) spacer. Both SPDP handles participate in thiol-disulfide exchange with free sulfhydryls to yield reversible disulfide bonds. The symmetric design facilitates disulfide-mediated crosslinking between two thiol-containing entities. The PEG11 chain ensures strong water solubility.
