Description and Uses

MBS is a heterobifunction crosslinker that contains a maleimide group which is reactive towards sulfhydryls and an NHS ester, useful for targeting amine groups.

3-Maleimidobenzoic acid N-hydroxysuccinimide ester is a heterobifunctional coupling reagent useful for forming enzyme immunoconjugates. The reactive groups are the NHS ester and maeimide.
