Mal-PEG-SCM (MW 1000)

Mal-PEG-SCM (MW 1000) is a linear heterobifunctional PEG compound featuring maleimide and NHS ester succinimidyl groups. As a crucial PEG-linked crosslinker, maleimide reacts with thiols, SH groups, and sulfhydryls, while SCM, representing succinimidyl carboxymethyl, interacts with primary amines. The maleimide moiety contains a reactive C=C double bond that is sensitive to light and oxygen.
