Dyes and Fluorophores 

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.
