HS-PEG-SH

Alpha,omega-dithiol poly(ethylene glycol) (HS-PEG-SH) is a homobifunctional precision PEG derivative with a defined chain length. Both ends bear thiol groups. Discrete chain lengths with different degrees of polymerization are available. The thiol can add to maleimides or participate in disulfide formation, offering different molecular conjugation routes. Identical reactive sites at both ends support molecular bridging or derivatization on both sides. The conjugation scheme can be designed around the number of target sites.
