Safranin
Description
Safranin is one of the most established dyes for measuring mitochondrial membrane potential by fluorometry. It is an extrinsic fluorophore with an excitation wavelength of 495 nm and emission wavelength of 587 nm.
Abbreviation: Saf

Synonyms
Safranin O, Safranin Y, Saranin T, Gossypimine, Cotton Red, Basic Red2
Application in high-resolution respirometry
Safranin is a potent inhibitor of Complex I-linked respiration and of the phosphorylation system. At a concentration of 2 µM, safranin can be applied for simultaneous monitoring of oxygen consumption and mtMP of mt-preparations in a CII-linked substrate state.[1]
