Aplicação

4,4′-Diisothiocyanatostilbene-2,2′-disulfonic acid disodium salt hydrate has been used:
  • as band3 protein inhibitor in rabbits(19)
  • for the inhibition of bicarbonate transporters in brain slice tissue(20)
  • as HCO3-/Cl- exchanger (anion exchanger) in embryos(21)

A negatively charged homobifunctional cross-linking reagent. The isothiocyanate groups react with primary amines at pH 9.0-10.0.

Ações bioquímicas/fisiológicas

4,4′-Diisothiocyanatostilbene-2,2′-disulfonic acid is an anionic alkylating agent containing isothiocyanate residue. It is a negatively charged homobifunctional cross-linking reagent. 4,4′-Diisothiocyanatostilbene-2,2′-disulfonic acid is a specific inhibitor of cellular anion permeability used in cell transport studies. The isothiocyanate groups react with primary amines at pH 9.0-10.0. 4,4′-Diisothiocyanatostilbene-2,2′-disulfonic acid alkylates lysine residues and inhibits apoptosis indirectly by targeting membrane based anion transporters.In addition, it also inhibits calcium transport in vesicles.
A specific inhibitor of cellular anion permeability used in cell transport studies.
