4-Arm PEG-SC

Synonyms: Four-Arm polyethylene glycol-Succinimide carbonate; Four-Arm PEG-SC; Four-Arm polyethylene glycol-SC

Four-Arm polyethylene glycol-Succinimide carbonate (4-Arm PEG-SC) is a kind of multi arm peg derivative with four identical peg branches, which can be used to modify proteins, peptides, particles and other materials. It is usually viscous or solid, soluble in organic solvents and water, and can be stored for a long time at -20℃. Four arm polyethylene glycol derivatives have a variety of active groups that can be used to modify proteins, peptides and other materials through their functional groups. Succinimide methyl ester can form stable amide bond with amino group. PEG can increase the solubility and stability of the drug, reducing the immunogenicity of peptides and proteins, and inhibit the non-specific binding of charged molecules on the modified surface.
