4,4''-Diaminostilbene-2,2''-disulfonic Acid Disodium Salt is an intermediate in the synthesis of 4,4''-Diisothiocyano-2,2''-stilbenedisulfonic Acid, Disodium Salt. Stilbene disulfonates have been employed to inhibit anion transport in a large number of mammalian cell types (GABA, Cl-). Some stilbene disulfonates can bind specifically to proteins that are not anion transporters. DIDS reacts with CD4 glycoprotein on T helper lymphocytes and macrophages, blocking HIV type-1 growth at multiple stages of the viral life cycle.Fluorescence: max. Abs. l = 341, max.
