Description
General Description
Poly(L-Glutamic Acid) (pGlu) is a naturally derived biodegradable polyanionic polymer consisting of repeating L-glutamic acid units linked through peptide bonds. The abundant pendant γ-carboxylic acid groups provide numerous reactive sites for chemical modification using EDC/NHS coupling or other peptide-coupling chemistries, making pGlu an excellent platform for preparing multifunctional biomaterials.
The polymer exhibits excellent water solubility, biocompatibility, and biodegradability. It is enzymatically degraded into naturally occurring L-glutamic acid, minimizing toxicity and making it highly attractive for pharmaceutical and biomedical applications.
Poly(L-Glutamic Acid) has been extensively investigated as a carrier for anticancer drugs, proteins, peptides, nucleic acids, and imaging agents. It is also widely used for hydrogel preparation, nanoparticle stabilization, tissue engineering, regenerative medicine, and surface modification.
