GA-PEG-GA, MW 600-35k

GA-PEG-GA has two identical activated carboxyl terminal groups, which can also be condensed with a hydroxyl group to give an ester bond. This homobifunctionalized PEG derivative has wide applications in peptides, proteins, lipids, other small molecules and surface modifications. Drug PEGylation can alter its dispersity and solubility in aqueous solutions. PEG modification can create a spatial barrier around the drug, reduce the enzymatic hydrolysis of the drug, avoid the rapid elimination of kidney metabolism, and allow the drug to be recognized by cells of the immune system.
