EMCS


An amine-to-sulfhydryl crosslinker with a medium-length spacer arm (9.4 angstroms).

Pierce EMCS

Thermo Scientific Pierce EMCS is an amine-to-sulfhydryl crosslinker that contains NHS-ester and maleimide reactive groups at opposite ends of a medium-length spacer arm (9.4 angstroms).

Highlights:

  • Reactive groups: NHS ester and maleimide
  • Reactive towards: amino and sulfhydryl groups
  • C6-homolog of aliphatic spacer series which includes AMAS, BMPS, GMBS and EMCS
  • NHS ester end couples with primary amines at pH 7-9 to form stable amide bonds
  • Maleimides react with -SH groups at pH 6.5-7.5, forming stable thioether linkages
  • Non-cleavable
  • Water-insoluble (dissolve first in DMF or DMSO); compare to Sulfo-EMCS
  • Increased sphere of coupling vs. GMBS
  • Short aliphatic spacer has low potential for eliciting an immune response
