Description
mPEG(5k)-PLLA(2k)-COOH contains a monodisperse PEG chain of 5k molecular weight linked to a PLLA segment of 2k, terminating with a carboxylic acid (COOH) group. The COOH group allows for amide coupling reactions with primary amines.
Applications
mPEG(5k)-PLLA(2k)-COOH has good water solubility and biocompatibility, and can be used as a carrier to achieve slow release, controlled release and targeted delivery of active molecules by adjusting the ratio of PLLA and mPEG as well as the modification of carboxyl functional groups.
