Abstract
Cell counts that distinguish between live and dead cells while providing an accurate count of the total of live and dead cells are obtained by the use of a vital stain in conjunction with illumination of the cell population and the taking of light images at different wavelengths, one which is not absorbed by the stain and one that is absorbed by the stain. Masking and inaccuracies in the counting of dead cells is thereby avoided.
