8arm PEG Succinimidyl Succinate (tripentaerythritol) reagent with superior quality specification of ≥ 95% Substitution.
JenKem Technology’s 8arm PEG Succinimidyl Succinate (tripentaerythritol) derivatives can be crosslinked into degradable PEG hydrogels. 8arm PEG Succinimidyl Succinate (tripentaerythritol) is a cleavable PEG linker. The cleavable ester linker between PEG and NHS ester enables the feature of “degradable” 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. JenKem Technology’s 8 arm (TP) PEGs are synthesized by ethoxylation of tripentaerythritol. 8ARM(TP)-PEG polymers with tripentaerythritol core have a higher purity as evidenced by MALDI compared with the generic 8ARM-PEG polymers with a hexaglycerin core.
The number of ethylene oxide units in the PEG chain may not be equal for all arms. The total molecular weight reported for the JenKem multi-arm PEGs is the sum of the PEG molecular weights of each arm. Multi-arm star PEG products with molecular weights, branching, and functional groups not listed in our online catalog may be available by custom synthesis.
