WebThis is based on the principle that live cells contain intact cell membranes that eliminate certain dyes, like trypan blue, Eosin, or propidium. In dead cells, the stain enters the cytoplasm and the cells take on the stain. If more than 25% of the cells are stained, the cell suspension is most likely not a viable one. To prepare the counting ...
