Assays for Cell Health

Assays for Cell Health
Invitrogen offers a diverse selection of solutions for determining cell health.  Our products provide:

  • New technologies to give you the best readout for cell viability, cytotoxicity, and proliferation.
  • Multiple platform options that fit your research needs
  • Novel solutions to cumbersome, slow, and hazardous protocols

Although a lot of kits can be used for multiple types of assays, below are our recommendations for their use in determining cell proliferation, cell viability and cell cytotoxicity. For more details see our Cell Health Products Selection Guide.

The Countess™ Automated Cell Counter

Countess Cell Counter
The Countess™ Automated Cell Counter offers easy and accurate cell counting and viability counts. You can get all the data you need about your cell cultures in just 30 seconds without using a hemocytometer.

Cell Proliferation

Cell Proliferation
New DNA Synthesis

Superior cell proliferation analyses, just a click away: Click-iT® EdU—A superior alternative to tritiated (3H) thymidine or BrdU-based assays for measuring new DNA synthesis by flow cytometry, fluorescence microscopy or high-throughput imaging (HCS).



DNA Content

Count on CyQUANT® when you need an accurate determination of cell number. Because cell DNA content is constant, measuring cell number using DNA provides an accurate indication of relative cell number.

Cell Viability

Cell Viability
LIVE/DEAD® Kits for Cell Viability

Invitrogen offers complete solutions for easy, sensitive determination of cell viability, cell vitality and compound cytotoxicity.  These fluorescence-based LIVE/DEAD® assays can be used to examine animal cells, bacteria, yeast and fungi. Specific LIVE/DEAD® assays can be used for flow cytometry, microscopy, or microplate formats.



PrestoBlue™ Cell Viability Reagent

PrestoBlue™ reagent is a resazurin-based solution that functions as a cell viability indicator by using the reducing power of living cells to quantitatively measure the proliferation of cells.  This assay is compatible with primary cells and allows for continuous live cell monitoring after measurement of cell viability.
