Guava Technologies claims the ViaCount assay 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.
The Guava ViaCount assay provides rapid cell counts and viability determination based on the differential uptake of fluorescent reagents.
The Guava ViaCount assay uses proprietary easy-to-use Guava software, and reagent kits optimised for use with the Guava PCA and PCA-96 systems.
Using a Guava personal cell analysis system, with ViaCount reagent, you can automatically obtain absolute cell counts and viability results.
The Guava ViaCount method is typically ten times faster than traditional manual counting methods allowing you to better maintain optimal tissue culture / bioreactor conditions.
Unlike conventional cytometer systems the Guava ViaCount method doesn't require beads for absolute counts and thus is inherently more precise and accurate than other instruments.
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.
Guava Technologies, a privately held biotechnology company, is a provider of on-demand, easy-to-use single cell analysis systems.
Guava Personal Cell Analysis (PCA) systems, including the Guava PCA, Guava PCA-96, Guava EasyCyte and EasyCyte Mini systems, are integrated, fully optimised, microcapillary cytometry systems with embedded absolute cell counting capability.
Used worldwide by the life sciences, biotechnology, and pharmaceutical industries, as well as clinical testing institutions (outside the United States and Europe), Guava's products have broad applications in scientific research and throughout the drug discovery and lead optimisation process, as well as for cell counting and optimisation of commercial biopharmaceutical production.
Guava offers a variety of assays and dedicated software modules for the Guava PCA systems, enhancing the system's overall ease-of-use.
