Sulfo-MBS crosslinker (m-Maleimidobenzoyl-N-hydroxysulfosuccinimide ester) is a non-cleavable, water soluble, heterobifunctional protein crosslinking reagent that is commonly used to crosslink haptens to carrier proteins and enzymes to antibody. The Sulfo-MBS crosslinking reagent"s NHS ester and maleimide reactive groups react with amine and sulfhydryl moites, respectively.MBS crosslinker is the water insoluble analog of Sulfo-MBS crosslinker which is also offered by ProteoChem.SATA Protein Modifier can be used to add sulfhydryl groups (thiols, -SH) to proteins or peptides prior to Sulfo-MBS crosslinking.Molecular Weight: 416.29CAS: 92921-25-0Spacer Length: 7.3 ÅAlternative Names: 3-Maleimidobenzoic acid N-hydroxysulfosuccinimide ester; meta-Maleimidobenzoyl-N-hydroxysulfosuccinimide ester; Sulfo MBSSpecial bulk pricing is available on bulk quantities of Sulfo-MBS crosslinker for your large volume manufacturing application.
