Description

Sulfo-SIAB is supplied as a sodium salt and is water-soluble to ~10mM. SIAB must be first dissolved in an organic solvent, such as DMSO or DMF, and then added to the aqueous reaction mixture. SIAB is lipophilic, membrane-permeable and does not possess a charged group.

Bearing the sulfo-NHS ester and iodoacetyl reactive groups, which react selectively with amino and sulfhydryl groups repsectively. This is a non-cleavable linker and is a more soluble alternaive to SIAB.
