[Flow cytometric analysis using live/dead staining for yeast cells which were autoclaved and treated with various disinfectants].

Flow cytometric analysis using live/dead staining dyes was applied to discriminate yeast cells treated with autoclave and various disinfectants. One fluorogenic dye, propidium iodide cannot leak into live cells with intact membranes, whereas another fluorogenic dye, thiazole orange is permeant and can enter all cells, live and dead. Thus a combination of these two dyes can classify cell populations into live, injured and dead cells.
