PLGA(20k)-PEG(1k)-MAL is an amphiphile polymer with hydrophobic poly(lactide-co-glycolide) (PLGA) and hydrophilic PEG. The self-assembling polymer forms micelles which can be used to entrap hydrophobic drugs. The terminal maleimide can react with thiol (SH) via thioether bond formation. Reagent grade, for research purpose.
