Description
General Description
PLGA-Amine (PLGA-NH2) is a functionalized biodegradable polymer derived from poly(D,L-lactide-co-glycolide) with a 50:50 lactide composition. The 50:50 PLGA composition exhibits one of the fastest degradation rates among PLGA copolymers, making it particularly attractive for controlled drug release and transient biomedical applications.
The terminal primary amine group serves as a versatile reactive site for covalent attachment of peptides, proteins, antibodies, fluorophores, imaging agents, nucleic acids, and targeting ligands. Conjugation is commonly achieved using NHS esters, activated carboxylic acids, aldehydes, isothiocyanates, and other amine-reactive reagents.
PLGA-NH2 (50:50) is widely utilized in nanoparticle preparation, targeted drug delivery, tissue engineering scaffolds, injectable biomaterials, and advanced nanomedicine research.
