Thermo Fisher, 22317, Sulfo-SMPB (sulfosuccinimidyl 4-(N-maleimidophenyl)butyrate)

Sulfo-SMPB (sulfosuccinimidyl 4-(N-maleimidophenyl)butyrate) Thermo Scientific Pierce Sulfo-SMPB is a water-soluble amine-to-sulfhydryl crosslinker that contains NHS-ester and maleimide reactive groups at opposite ends of a medium-length aromatic spacer arm (11.
6 angstroms).
Features of Sulfo-SMPB:
•Reactive groups:sulfo-NHS esterandmaleimide
•Reactive towards: amino and sulfhydryl groups
• Extended chain length limits steric hindrance
• Non-cleavable
• Water-soluble (compare toSMPB)
• Membrane impermeable, allowing for cell surface labelingProduct References:Crosslinker Application Guide -- search for recent literature references for this productCell Permeability: No
