mPEG-Folate

Methoxy-poly(ethylene glycol)-folic acid (mPEG-Folate) is a monofunctional precision PEG derivative with a defined chain length. One end bears a methoxy group. The other end bears a folate group. Discrete chain lengths with different degrees of polymerization are available. The folate terminus supports ligand presentation and receptor-related binding studies, allowing ligand position and PEG chain length to be varied independently. 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.
