Description

The iodoacetamide derivative of stilbene (4-acetamido-4'-((iodoacetyl) amino)stilbene-2,2'-disulfonic acid, disodium salt) is readily conjugated to thiols. The combination of high polarity and membrane impermeability makes this polysulfonated dye useful for determining whether thiol-containing proteins and polypeptide chains are exposed at the extracellular or cytoplsamic membrane surface. Stilbene protein adducts are charged and can be detected by gel or capillary electrophoresis.
For Research Use Only. Not for use in diagnostic procedures.
