Notes

There don't appear to be any dyes that selectively stain live cells. When people want to detect live cells, I think that what they do is the following: "The principle of this approach is to use simultaneously a permeant (SYBR Green [more recently SYTO green]; Molecular Probes) and an impermeant (propidium iodide) probe and to take advantage of the energy transfer which occurs between them when both probes are staining nucleic acids. A full quenching of the permeant probe fluorescence by the impermeant probe will point to cells with a compromised membrane, a partial quenching will indicate cells with a slightly damaged membrane, and a lack of quenching will characterize intact membrane cells identified as viable." From Applied and Environmental Microbiology, October 2001, p. 4662-4670, Vol. 67, No. 10. So most stains that people bill as live cell stains are only membrane permeant stains and therefore stain both live and dead cells.
