CardioGlo™-Tox HT: An in vitro standardized and validated ATP bioluminescence cardiotoxicity testing and screening platform


  • Cardiomyocytes have high intracellular concentrations of ATP. Changes in cardiomyocyte metabolism can be detected and measured using CardioGLO™-Tox HT.
  • Can be used with cardiomyocytes from different species as well as human ES or iPS-derived cardiomyocytes.
  • Specifically designed to screen and test for in vitro cardiotoxicity.
  • High throughput capability during in vitro ADME/Tox screening.
  • Allows drug and species ranking of toxicity.
  • Incorporates proven, standardized and validated ATP bioluminescence technology, the most sensitive signal detection system available.
  • Includes all reagents to calibrate and standardize the assay.
  • Measurement assurance parameters included to ensure the assay is working correctly.
  • Reliably compare results over time and between drug lots.
  • Assay kits include everything needed to perform the readout.
  • 96-Well plates included with all kits and available for adherent or non-adherent cells.
  • Available as 2- or 4-plate assay kits. Custom sizes also available.
  • Designed for multiplexing capability.
  • Rapid turnaround.
  • Simple and time efficient.

Principle of ATPBioluminescence Cell Proliferation/Cytotoxicity Assays

All ATP bioluminescence assays kits from Preferred Cell Systems™ include an ATP standard(s) and controls.  Performing the ATP standard curve and controls is highly recommended. The controls are used to calibrate the luminescence plate reader and the ATP standard is used to standardize the assay. The values obtained from the standard curve and controls (see diagram below) are then compared to the measurement assurance parameters that are provided in the instruction manual. If the values obtained are within the ranges provided by the measurement assurance parameters, you, the user, have successfully performed the proficiency testing to ensure that you have not only performed the assay correctly, but that the results you obtain can be trusted.

No additional proficiency testing is required if the calibration and standardization procedure is performed. The values you obtain from each calibration and standardization can be logged and used for certification that the assay has been performed correctly and that the results are trustworthy.

CardioGLO™-Tox HT can be used with cardiomyocytes from different species as well as human ES- or iPS-derived cardiomyocytes.

CardioGLO™-Tox HT assays are available with 96-well plates. Upon request, kits with 384-well plates are also available.

For Research Use Only. Not for clinical diagnostic use.

  • IMDM base medium for dilution of ATP standard.
  • ATP standard.
  • ATP controls.
  • ATP Enumeration Reagent.
  • Sterile, solid white 96-well plates. Available for adherent or non-adherent cells.
  • Non-sterile, solid, white 96-well plates.
  • Sterile, adhesive foil covers to maintain sterility of unused wells.
CardioGLO™-Tox HT is flexible so that the investigator can use there own growth medium to culture the cells.
