8-ArmPEG-Succinimidyl Glutarate ester (8-Arm PEG-SG) is a multiarmed PEG derivative with succinimidyl NHS ester groups at each terminal of the eight arms connected to one hexaglycerol core, which can be crosslinked into degradable PEG hydrogels. PEG hydrogels have a variety of applications in medical devices and regenerative medicine and are especially of interest for controlled release of drugs, for 2D and 3D cell culture, and for wound sealing and healing.  PEG-SG (succinimidyl glutarate ester) is one type of PEG-NHS reagents. There is a C4 hydrocarbon ester linkage between PEG and the NHS ester.
