4-ArmPEG-SG is a multi-arm PEG derivative with succinimidyl ester at each terminal of the four arms that can quickly react with primary amine. It can be can be crosslinked into degradable PEG hydrogels. 4-ArmPEG-SG is available with molecular weight of 2K, 5K, 10K, and 20K Da. Other MW may be available by custom synthesis. PEG hydrogels are widely used in a variety of biomedical applications, such as cell culture, wound sealing, and wound healing.
