HS-PEG-(γ)PGA

HS-PEG-(γ)PGA (sulfydryl-polyethylene glycol-poly-L-glutamic acid) is a linear amphiphilic block copolymer with poly-L-glutamate as hydrophobic part and sulfydryl functionalized PEG as hydrophilic part. HS-PEG-(γ)PGA can self-assemble into micelles. The -SH group on the PEG chain can react with biomolecules or small molecules containing -MAL group. It is a solid or semisolid which depends on its molecular weight. The bigger the molecular weight, the more likely it is to be a solid. HS-PEG-(γ)PGA can be widely used as drug carriers in targeted drug delivery system.
