SBAP


A short, NHS-ester and bromoacetyl crosslinker for amine-to-sulfhydryl conjugation.

Pierce SBAP

Thermo Scientific Pierce SBAP is a short (6.2 angstrom) crosslinker for amine-to-sulfhydryl conjugation via N-hydroxysuccinimide (NHS) ester and bromoacetyl reactive groups.

Highlights:

  • Reactive groups: NHS ester and bromoacetyl
  • Reactive toward: amino and sulfhydryl groups
  • NHS ester reacts with primary amines at pH 7-9 to form a stable amide bond
  • Bromacetyl group reacts with sulfhydryl groups at pH > 7.5 to form stable thioether bonds
  • Non-cleavable
  • Water-insoluble (dissolve first in DMF or DMSO)
  • Spacer maintains peptide-like character in the crosslinked species
  • Resulting crosslink is susceptible to acid hydrolysis
  • Useful for preparing cyclic peptides and peptide conjugates
