Abstract

A simple, rapid and reliable method has been developed for assessing the number and viability of cells, as well as cell size, in suspension culture by the use of flow cytometry. Propidium iodide exclusion is used for viability determination and fluorescent beads serve as an internal standard for cell enumeration. The main advantages of this method are its ability to handle a large number of samples with a high degree of precision and its specificity in detecting viable cells quantitatively in a heterogeneous culture of living and dead cells and debris. The method shows only a fraction of the variation found in the haemacytometer/trypan blue counting method due to its very low operator dependence. CHO - Chinese hamster ovary; FCS - Foetal calf serum; FS - Forward scatter light; MTT - 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide; NCS - newborn calf serum; PBS - Phosphate buffered saline; PI - Propidium iodide; SS - Side scatter light.
