Description

8-Arm PEG-GA is a multiarmed PEG derivative with carboxylic acid at each terminal of the eight arms connected to one hexaglycerol core. GA stands for glutamic acid. There is a C4 ester linkage between PEG and COOH. The ester linkage may be useful in reversible pegylation design. PEG acid can be used to react with amine groups with peptide coupling reagents.
