What follows is an informal compilation of
the voltage-sensitive dyes that have been used in a variety of preparations.
The information includes dye source, signal size, staining conditions,
and pharmacological- and photo-toxicity. In a few instances several
dyes have been tested. In some cases the data is presented directly,
in others a reference is given, and in some cases both. You can
contact the individual scientist directly for additional or more
up-to-date information.
The dyes with the label WW were synthesized by Jeff Wang and Alan
Waggoner, then at Amherst College. Dyes labeled RH were synthesized
by Rina Hildesheim and Amiram Grinvald at the Weizmann Institute.
Dyes labeled JPW were synthesized by Joe Wuskell and Les Loew at
the University of Connecticut Health Center. We depend on them.
Dissolving the dyes can be tricky in that they may look dissolved
but still be in small crystals. You can check this out by filtering
through a Millipore filter. If the dye was not dissolved, try modest
warming (e.g. 50°C). Hydrophobic dyes will require more extensive
procedures involving ethanol and Pluronic F127.

30 dyes were tested
(twenty pyrazolone-oxonols molecules, five merocyanine dyes,
three barbituric-acid oxonol dyes, and 2 styryl dyes; see
legend to Fig.3). The best results were obtained with two
positively charged pyrazolone-oxonol dyes (JPW1177 and JPW1245),
and two negatively charged merocyanine dyes (WW375 and JPW1124).
The relative signal size for the best four: 1.
