mPEG-Mal

Methoxy-poly(ethylene glycol)-maleimide (mPEG-MAL) is a monofunctional precision PEG derivative with a defined chain length. One end bears a methoxy group. The other end bears a maleimide group. Discrete chain lengths with different degrees of polymerization are available. The maleimide can add to cysteine thiols or other thiolated modules, providing a handle for conjugation at thiol sites. 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.
