Application:	3,3′-Dipropylthiacarbocyanine iodide has been used to determine bacterial membrane permeability by the effect of electrochemical scaffold treatment.
Biochem/physiol Actions:	The embrane potential sensitive dye, 3,3′dipropylthiacarbocyanine iodide enters only depolarized cells, where it binds reversibly to lipid-rich intracellular components.
General description:	3,3′-Dipropylthiacarbocyanine iodide is a carbocyanine fluorescent dye sensitive to membrane potential. This cyanine dye plays a vital role as an optical probe of membrane potential. An increase in the fluorescence intensity of the dye indicates depolarization of the plasma membrane potential.
Packaging:	250 mg in glass bottle
