Product Usage

Nuobichun (Shanghai) Chemical Co., Ltd. provides high-quality 4-arm polyethylene glycol succinimide succinate (4-arm PEG-SS) PEG active derivatives, which are multi arm PEG derivatives with succinimide based NHS active ester groups at each end of the 4-arm connected to a pentaerythritol core. 4-arm PEG-SS (succinimide succinate) is a PEG-NHS reagent. There is a C2 hydrocarbon ester bond between PEG and NHS ester. NHS is a good leaving group that can react with amine containing moieties.

4-arm PEG-SS is mainly used for academic research, innovative drug development, disease research, peptide PEG derivative modification, nanomodification, and other biological research, such as monoclonal antibodies, polyclonal antibodies, proteins, and biological reagents.
