Method:CellCountsUsingaHemacytometer
Method: Cell Counts Using a HemacytometerJune 1, 1990Rosalie VeilePurpose:The purpose of this procedure is to determine the cell density of the culture. Cell cultures always have some dead cells; the viable and non-viable cells can be distinguished with the use of trypan blue dye and a hemacytometer. Living cells will not take up the dye while dead cells do.Time required:5 minutes for 2 two cell countsProcedure:Trans......閱讀全文
