DTME


A mid-length, maleimide crosslinker with an internal disulfide bond for reversible sulfhydryl conjugation.

Pierce DTME

Thermo Scientific Pierce DTME is a mid-length, maleimide crosslinker for reversible covalent conjugation between sulfhydryl groups (e.g., protein or peptide cysteines) by reduction of the disulfide bond in the center of the spacer arm.

Highlights:

  • Reactive groups: maleimide (both ends)
  • Reactive towards: sulfhydryl groups
  • Long (13.3A), cleavable, sulfhydryl-to-sulfhydryl crosslinker, composed of maleimide groups and 11-atom disulfide spacer arm
  • Water-insoluble – dissolve first in DMF or DMSO, then add to aqueous reaction buffers
  • Cleavable by reduction of disulfide spacer arm with DTT, TCEP or other reducing agent
