di-SFA is a fluorescent probe used to measure transmembrane potential (Vm) across the plasma membrane. di-SFA contains a 3-hydroxychromone fluorophore that undergoes excited-state intramolecular proton transfer (ESIPT), producing dual emission from the normal (N*) and tautomeric (T*) states. di-SFA inserts deeply into the hydrophobic region of lipid bilayers. The sulfonate groups give di-SFA a double negative charge in aqueous media. Ratiometric measurements are performed in lipid vesicles using Ex/Em = 450/527 nm and Ex/Em = 450/605 nm.
