4-ArmPEG succinimidyl succinate (4-arm PEG-SS) is a high-quality multi-arm PEG derivative with succinimidyl succinate at each terminal of the four arms connected to one pentaerythritol core. It can be crosslinked into degradable PEG hydrogels, which can be used 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. 4-arm PEG-SS is available with molecular weights of 2K, 5K, 10K, 20K Da. Other MW may be available by custom synthesis.
