Description

Thermo Scientific Pierce SIA is a very short (1.5 angstrom) crosslinker for amine-to-sulfhydryl conjugation via N-hydroxysuccinimide (NHS) ester and iodoacetyl reactive groups.

Features of SIA:

Reactive groups: NHS ester and iodoacetyl
Reactive toward: amino and sulfhydryl groups
• Shortest sulfhydryl-reactive and amine-reactive heterobifunctional crosslinker available; compare to SIAB
• NHS ester reacts with primary amines at pH 7-9 to form a stable amide bond
• Iodoacetyl group reacts with sulfhydryl groups at pH > 7.5 to form stable thioether bond
• Non-cleavable
• Water-insoluble (dissolve first in DMF or DMSO)
