Mal-PEG-SCM (MW 10000) is a linear hetero-bifunctional PEG product with maleimide and succinimidyl NHS ester groups. Mal-PEG-SCM (MW 10000) is an important cross-linker with PEG chains. Maleimide reacts with thiols, SH, sulfhydryls or sulfhydryls, and SCM stands for succinimidyl carboxymethyl ester, which reacts with primary amines. Maleimide contains a reactive C=C double bond and is sensitive to light or oxygen[1].
