Cell viability is defined as the percentage of live cells within the total population. The determination of yeast cell viability is commonly used to assess the impact of various types of stressors in toxicity research and in industrial microbiology studies. The yeast Saccharomyces cerevisiae is a useful and widely used model organism used for studies of cyto- or genotoxicity under various chemical, physical, or environmental conditions.
Cell viability analysis is also critical in industrial applications involving microorganisms, such as food, beverage, and biofuel production. Classizer™ ONE provides an accurate estimation of the cell viability even in the presence of secondary populations and impurities.
In comparison with fluorescence kits available on the market, SPES / SPES² offer major advantages:
- Automatic measurement of tens of thousands of cells
- Fast measurement, requiring just a few minutes/sample
- No need for expensive consumables
- Minimal or even no sample preparation, except for a simple and automatable pre-dilution
- Inline/online monitoring for industrial applications
