Load a hemacytometer and examine immediately under a microscope at low magnification. 5. Count the number of blue staining cells and the number of total cells. WebThe aliquot should contain a convenient number of cells to count in a hemacytometer when suspended in 1 ml PBS and then diluted again by mixing with 0% trypan blue (e., 5 × 105 cells/ml). Resuspend the cell pellet in 1 ml PBS or serum-free complete medium. Serum proteins stain with trypan blue and can produce misleading results.
