GMBS


An amine-to-sulfhydryl crosslinker with a short spacer arm (7.3 angstroms).

Pierce GMBS

Thermo Scientific Pierce GMBS is an amine-to-sulfhydryl crosslinker that contains NHS-ester and maleimide reactive groups at opposite ends of a short spacer arm (7.3 angstroms).

Highlights:

  • Reactive groups: NHS ester and maleimide
  • Reactive toward: amino and sulfhydryl groups
  • C4-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-GMBS
  • Short aliphatic spacer has low potential for eliciting an immune response
