  • Product overview

    Abcam's Cell Viability Assay Kit (Bioluminescent) utilizes bioluminescent detection of the ATP levels for a rapid screening of apoptosis and cell proliferation simultaneously in mammalian cells. The assay utilizes luciferase to catalyze the formation of light from ATP and luciferin, and the light can be measured using a luminometer or Beta Counter. The assay can be fully automatic for high throughput (10 seconds/sample). The high sensitivity of this assay has led to many other applications for detecting ATP production in various enzymatic reactions, as well as for detecting low level bacterial contamination in samples such as blood, milk, urine, soil, and sludge.

  • Notes

    Cell death (especially apoptosis) is an energy-dependent process that requires ATP. As ATP levels fall to a point where the cell can no longer perform basic metabolic functions, the cell will die. A typical apoptotic cell exhibits a significant decrease in ATP level. Therefore, loss of ATP level in cell has been used as an indicator of cell death. In contrast, cell proliferation has been recognized by increased levels of ATP.

  • RelevanceCell viability is a determination of living or dead cells, based on a total cell population. Cell viability assess healthy cells in a sample, with no distinction between dividing or quiescent cells. An increase in cell viability indicates cell growth, while a decrease in viability can generally be interpreted as the result of either toxic effects of compounds/agents or suboptimal culture conditions.

I've confirmed with the lab, and you can use this kind of media but be sure to use a control media with the same amount of RPMI and FBS to account for any signals generated due to these 2 in your sample readings. Just subtract the control rea...

Yes, you are correct. Lower ATP readings would indicate a decrease in cell viability.

Ab65314 is recommended for cell viability. For media, use the same protocol as mentioned for the suspension cells in step 2.a.

Thank you for contacting us and for asking your question about the Cell Viability Assay Kit instructions.

The instruction on page 7 of the protocol to read the samples for one minute after adding the enzyme is mistaken. It should read:

Thank you for your reply. I can confirm that conventional scintillation counters can not be used for measurements with this kit. However, when Beta Counter is used it should be programmed in the “out of coincidence” (or Luminescence mode) for m...
