Product Name: 4-arm-PLGA, MW 40K
Polymer Composition: Four-Arm Poly(lactic-co-glycolic acid) (Hydroxyl-terminated)
4-arm-PLGA, MW 40K is a high molecular weight star-shaped biodegradable polyester with a pentaerythritol core and four hydroxyl-terminated PLGA arms. Its four-branched structure offers higher terminal group density and enhanced crosslinking capacity relative to linear PLGA. The material exhibits excellent biocompatibility and adjustable degradation profiles, and can be further chemically modified to generate various PLGA derivatives. It is broadly adopted for polymeric nanoparticle synthesis, long-term sustained drug delivery, injectable hydrogels, tissue engineering scaffolds and cutting-edge biomedical material research.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
