ViaQuant™ Cell Viability/Cytotoxicity Assay


Our ViaQuant™ Cell Viability/Cytotoxicity Kits are principally used to enumerate the proportion of live and dead cells in a population. The fluorescence-based cell viability and cytotoxicity assays are less hazardous and less expensive than radioisotopic techniques, more sensitive than colorimetric methods and more convenient than animal testing methods. Our cell viability and cytotoxicity assays are reliable and easy to perform for simultaneous quantitation of live and dead cells. Our kits are suitable for detection with a fluorescence microscope, flow cytometer or microplate reader, and ideal for high-throughput screening applications.


  • Simplicity: Reagents are simultaneously added, no wash steps are required
  • Specificity and reliability: Distinct color for live and dead cell
  • Versatility: Suitable for fluorescence microscope, flow cytometer or microplate reader
