The styryl dye RH237 is a fast-responding potentiometric probe that is primarily used for functional imaging of neurons. Excitation/emission data (below) is for the dye in methanol. In cell membranes, the spectra of styryl dyes are typically blue-shifted by as much as 20 nm for absorption or excitation and 80 nm for emission.
- λEx/λEm (MeOH) = 528/782 nm
- Dark solid soluble in DMSO
- Store at -20°C and protect from light
- MW: 496.71
