8 Arm PEG Succinimidyl Succinate (8-arm PEG-SS) derivatives can be cross-linked into degradable PEG hydrogels. It is a cleavable PEG linker. The cleavable ester linker between PEG and NHS ester enables the feature of degradable 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. 8-arm PEG-SS is available with molecular weights of 2K, 5K, 10K, 20K Da. Other MW may be available by custom synthesis.
