✦ Synopsis

Flow cytometry offers the possibility to simultaneously analyze, on a cell by cell basis, different parameters related to cell viability i.e. cell size, morphology and incorporation of dyes. Different types of analysis: light absorption of unstained/stained cells, forward angle light scattering (FALS), right angle light scattering (RALS) or both, cell fluorescence based on dye retention or dye exclusion (due to erythrosin B, ethidium bromide, fluorescein diacetate, rhodamine 123) were tested and compared, with the classical Trypan blue exclusion test, for their effectiveness in the determination of cell viability. Two types of cells in monolayer cultures (L929, SIRC) and a freshly isolated suspension of mouse splenocytes were used. For each dye, the optimal dose, incubation time and conditions for analysis were determined. Viability indications by different techniques for the three type of cell line and their reliability as compared with Trypan blue were analyzed.
