Description
General Description
Poly(L-Glutamic Acid)-PEG-Poly(L-Glutamic Acid) is an amphiphilic ABA triblock copolymer designed for advanced drug delivery and biomaterial applications. The central PEG block improves aqueous solubility, prolongs circulation time, enhances biocompatibility, and reduces nonspecific protein adsorption. The two biodegradable poly(L-glutamic acid) blocks contain abundant pendant γ-carboxylic acid groups that can be activated using EDC/NHS chemistry or peptide-coupling reagents for conjugation with drugs, proteins, peptides, antibodies, nanoparticles, and imaging agents.
The amphiphilic structure enables self-assembly into micelles and nanoparticles in aqueous media and allows the formation of biodegradable hydrogels through chemical or physical crosslinking. Upon biodegradation, the polymer yields PEG and naturally occurring L-glutamic acid.
pGlu-PEG-pGlu is widely employed in polymer-drug conjugates, nanomedicine, injectable hydrogels, controlled drug delivery, tissue engineering, regenerative medicine, and biomedical research.
