WebTo check the viability of your cell sample, dilute an aliquot of your cell suspension in trypan blue, and then load the trypan blue stained sample just like the regular cell sample. Under the phase contrast, the live cells will appear bright and golden and should be counted; do not count any of the dull, dead, blue cells. WebTo determine the accuracy of cell counts done with the LUNA™ Reusable Slide, cell counts were compared to those obtained manually with a hemocytometer. Cells were serially diluted and mixed with an equal volume of 0.4% trypan blue stain. 10 µL of the mixture was loaded into the LUNA™ Reusable Slide and a glass hemocytometer with Neubauer ...
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.
