4-Arm PLGA-COOH is a star-shaped biodegradable polymer functionalized with four carboxyl-terminated PLGA arms. Compared with linear PLGA-COOH, it achieves higher functional group density and superior conjugation efficiency. Terminal carboxylic acid groups support facile coupling to amine-containing molecules, suitable for drug delivery systems, nanoparticle surface modification, hydrogel preparation and biomaterial development.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
