u count dead cells stained by trypan blue. trypan blue enters the cells only when it has died since when a cell dies it looses its property of controlling selective inlet of micromolecules. When cells r alive it doesn't allow inlet of trypan blue so viable cells r not stained. viable cells = total cells - trypan blues stained cells Nitin Ghoshal Dept of Biotechnology NEHU, Shillong, Meghalaya, India

Why use citric acid in crystal violet staining?
Crystal Violet staining is a technique used in cell culture laboratories to determine concentration of cells in culture liquid. As against other means of cell staining and counting (e.g. Trypan blue) the entities counted using the Crystal Violet staining are the cell nuclei instead of whole cells. This technique has the advantage that also concentrations of aggregated cells can be determined accurately. Here comes the Citric acid in. Nuclei are situated within the cell. To extract the nuclei out of the cells Citric acid is used to make the cell burst so that the Crystal Violet can stain the nuleus and thus concentration of cells can be determined using a microscope and a counting chamber.
