Mal-PEG-SCM (MW 40000)

Mal-PEG-SCM (MW 40000) is a linear heterobifunctional PEG compound featuring maleimide and N-hydroxysuccinimide ester (NHS) functional groups. It serves as a significant PEGylated crosslinker. The maleimide group reacts with thiol, SH, mercapto, or sulfhydryl groups, while SCM stands for succinimidyl carboxymethyl, which can interact with primary amines. The maleimide includes a reactive C=C double bond that is sensitive to light and oxygen.
