MPEG-N3 (MW 5000)

MPEG-N3 (MW 5000) can be used to modify proteins, peptides, and other materials. The azide group can react with alkynes in aqueous solution catalyzed by copper. It can also be easily reduced to an amine group. PEGylation can increase solubility and stability and reduce the immunogenicity of peptides and proteins. mPEG-N3 (MW 5000) can also inhibit the nonspecific binding of charged molecules to the modified surface[1].
