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. The terminal succinimidyl groups are reactive toward primary amines, making 4-ArmPEG-SS useful as a crosslinker for degradable PEG hydrogels and other biomaterial systems.

4-ArmPEG-SS is widely 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.
