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. WebInstead of using trypan blue, 3% Acetic Acid with Methylene Blue can be used [3]. Using a hemocytometer can be quite time consuming when counting the number of cells. Other quantification methods such as Scepter cell counting can be used. The Scepter cell counter is an automated device which is handheld and used to count cells, monitor
