Product Information

• Name: 4-Acetamido-4'-isothiocyanatostilbene-2,2'-disulfonic Acid, Sodium Salt
• Synonyms: disodium;5-acetamido-2-[(E)-2-(4-isothiocyanato-2-sulfonatophenyl)ethenyl]benzenesulfonate
• Brand: TRC
• Description: Stability Hygroscopic, Temperature SensitiveApplications A fluorescent label for the specific and reversible labelling of the outer components of the plasma membrane. The reagent reacts with a fixed number of sites on the surface of cells concerned with anion permeation; does not pass through the osmotic barrier of the membrane; reacts under physiological conditions of temperature, pH and tonicity; and is detectable in small amounts.
