mPEG-SH

Methoxy-poly(ethylene glycol)-thiol (mPEG-SH) is a monofunctional precision PEG derivative with a defined chain length. One end bears a methoxy group. The other end bears a thiol group. 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. Capping one end defines the direction of derivatization, enabling the hydrophilic PEG segment to be attached to a target molecule and functional linkers of the required length to be constructed.
