Application
PEG-PLGA, is a biocompatible, amphiphilic block copolymer composed of a hydrophilic PEG block and a hydrophobic poly(lactide-alternative-glycolide) (PLGA) block. These materials have been used in control release and nanoparticle formulation for drug encapsulation and delivery applications.
Different from common Poly(lactide-co-glycolide) (PLGA) polymer, the lactic and glycolic units in Poly(lactide-alt-glycolide) block alternate in sequence in the polymer chain, and the molar ratio of lactic to glycolic units in the polymer is exactly 1:1.
Poly(lactide-alt-glycolide) exhibits excellent solubility in common organic solvents, such as acetonitrile, acetone, dioxane, DCM, and THF, providing great convenience for drug delivery researches and applications.
