4-Arm PEG vinyl sulfone
4 arm PEG derivatives have multiple reactive groups that can be used to modify proteins, peptides and other materials via their functional groups. PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces. .
- Off-white/white solid or viscous liquid depends on molecule weight;
- Soluble in regular aqeous solution as well as most organic solvents;
- Store at -20 0C, desiccated Protect from light. Avoid frequent thaw and freeze.
