Product Usage
Nuobichun (Shanghai) Chemical Co., Ltd. provides high-quality 4-arm PEG-MAL PEG active derivatives, which are multi armed PEG derivatives with maleimide groups at each end of the four arms connected to a pentaerythritol core. The maleimide group selectively reacts with free thiols through Michael addition SH、 Thiol or thiol groups react to form stable carbon sulfur bonds. 4-Arm PEG-MAL can be used for site-specific protein and peptide modification.
4-arm PEG-MAL 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. |
