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.

Features of SBAP:

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
