4arm-PEG-SG (4arm-PEG-Succinimidyl Glutarate) is a 4-arm PEG derivative with four terminal NHS glutaric acids, and a cleavable ester linker between PEG and NHS ester enables “degradable” hydrogelation properties of glue. Multi-armed PEG derivatives are commonly used in drug delivery systems. The molecular weight of the modified drug increases, and it is not easy to be metabolized and eliminated in the body.
