ViaCount™ Assay

Guava Technologies' ViaCount assay is revolutionizing the way cell counting and viability assessment are done in today's laboratories. 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:

• Cell counts up to ten times faster than manual counting, in a convenient turnkey assay.
• Accurate, reproducible counts with very low density cell samples or small sample volumes.
• Absolute cell counts, viability assessments and apoptotic cell counts in a single measurement. By providing data on all these cell populations in a single measurement, the Guava ViaCount assay enables a more precise evaluation of culture conditions and viable cell populations so you can best optimize culture conditions.
• Flexibility for many cell types. Accurately counts adherent, clumpy and even non-mammalian cells, such as insect cell lines.
• More experimental consistency. These precise, accurate cell counts can provide more consistency in experiments that require accurate viable cell counts for success, such as ELISpot, cell-based fluorescence assays or cytokine production assays.

The Guava ViaCount assay uses proprietary easy-to-use Guava software, and reagent kits optimized for use with the Guava PCA and PCA-96 systems.

Guava ViaCount is fast becoming the method of choice for monitoring cell culture or bioreactor conditions and cell count/viability assessments.
