　　产品描述：4 arm PEGderivatives have multiple reactive groups that can be used to modify proteins,peptides and other materials via their functional groups. PEGylation can increasesolubility and stability and reduce immunogenicity of peptides and proteins. Itcan also suppress the non-specific binding of charged molecules to the modifiedsurfaces.
