Description
General Description
PLGA-NH₂ (75:25) is a reactive biodegradable polymer containing poly(lactic-co-glycolic acid) (PLGA) with a 75:25 lactide:glycolide composition and a terminal primary amine group. The amine functionality enables conjugation with activated carboxylic acids, NHS esters, and other amine-reactive molecules for nanoparticle surface engineering, bioconjugation, and biomaterial functionalization applications.
The 75:25 lactide:glycolide ratio provides slower degradation behavior and enhanced hydrophobicity compared with lower lactide-content PLGA materials, making it suitable for sustained drug delivery and controlled release applications.
