Properties

Description

This heterobifunctional crosslinker features a free terminal thiol (sulfhydryl) group and a carboxylic acid separated by an octaethylene glycol (PEG8) spacer. The thiol group enables gold attachment, maleimide addition, or disulfide formation. The carboxylic acid allows amidation coupling with primary amino groups. The hydrophilic PEG8 spacer ensures excellent water solubility.
