A short-arm, maleimide crosslinker for sulfhydryl conjugation.

Pierce BMOE

Thermo Scientific Pierce BMOE is a short-arm, maleimide crosslinker for covalent, irreversible conjugation between sulfhydryl groups (e.g., protein or peptide cysteines).


  • Reactive groups: maleimide (both ends)
  • Reactive towards: sulfhydryl groups
  • Short (8.0A), sulfhydryl-to-sulfhydryl crosslinker, composed of maleimide groups and 7-atom spacer arm
  • Shortest bismaleimide crosslinker available for close proximity crosslinking
  • Water-insoluble – dissolve first in DMF or DMSO, then add to aqueous reaction buffers
  • Noncleavable
