Fast, automated and highly reproducible cell counting & viability assessment

26 Oct 2006

Product news

The ViaCount™ assay from Guava Technologies Inc. is revolutionising the way cell counting and viability assessment are done in life science laboratories around the world.

Fast, automated, and highly reproducible, the Guava ViaCount assay addresses many of the difficulties of conventional cell counting and viability assessment methods.

By providing absolute cell counts, viability assessment and apoptotic cell counts in a single measurement, the Guava ViaCount assay enables a more precise evaluation of culture conditions and viable cell populations so you can best optimise culture conditions. Furthermore the Guava ViaCount assay is very flexible - accurately counting adherent, clumpy and even non-mammalian cells, such as insect cell lines. The improved cell counting consistency delivered by Guava ViaCount is particularly important in experiments that require accurate viable cell counts, such as ELISpot, cell-based fluorescence or cytokine production assays.

Flow Cytometry / Cell CountingFlow cytometers are used to count, sort and examine multiple characteristics of cells. Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays.

This can reveal information on cell health (apoptosis, cytotoxicity, viability and proliferation assays), cell metabolism, cell migration and cell signaling mechanisms.
