Product Name: 4-arm-PLGA, MW 20K
Polymer Composition: Four-Arm Poly(lactic-co-glycolic acid) (Hydroxyl-terminated)
4-arm-PLGA, MW 20K is a star-shaped biodegradable polyester built upon a pentaerythritol core with four hydroxyl-terminated PLGA arms. The four-branched structure delivers higher terminal group density and superior crosslinking capability compared to linear PLGA. It possesses favorable biocompatibility and tunable degradation kinetics, and can undergo further chemical modification to produce diverse PLGA conjugates. It is widely utilized for polymeric nanoparticle fabrication, sustained drug delivery systems, injectable hydrogels, tissue engineering scaffolds and advanced biomedical material research.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
