Product Usage

Nuobichun (Shanghai) Chemical Co., Ltd. provides high-quality 4-arm PEG-SH PEG active derivatives, which are multi arm PEG derivatives with thiol groups at each end of the four arms connected to a pentaerythritol core. Active free thiols, SH, thiol or thiol selectively react with maleimide and transition metal surfaces including gold, silver, etc. PEG-SH is easily oxidized in air to form SS disulfide bonds, and reduction can reverse the proxy. It is an important product of reversible PEGylation and PEG hydrogel.

4-arm PEG-SH 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.
