Fully Standardized ATP Bioluminescence In Vitro Toxicity Assay Platform for ES, iPS or other stem cell lines.


Buy STEMGlo™-Tox HT Assay Kits

A standardized ATP bioluminescence toxicity testing assay platform for primary explanted cells, ES, iPS, cell lines and tumor cells.


  • High throughput in vitro toxicity screening and testing using embryonic stem (ES), induced pluripotent stem (iPS) cells or other stem cell lines.
  • Can be incorporated at any stage of drug development, including ADME/Tox.
  • Drug/agent toxicity ranking according to cell source and species.
  • Development of drugs and other therapies using stem cell gene targeting and expression research, e.g. CRISPR-Cas9.
  • A flexible, in vitro assay platform to perform high throughput toxicity testing.
  • Can be applied to numerous cell types derived from different organs, tissues and species.
  • High-throughput capability using 96- or 384-well plate formats allows ADME-Tox drug or compound screening, thereby significantly reducing unexpected results during pre-clinical testing.
  • A 3Rs Assay Platform-Helps Reduction, Refinement, Replacement for animal testing.
  • Available for adherent or non-adherent cell types.
  • 2D and 3D cell culture models.
  • Incorporates the most sensitive ATP bioluminescence readout available to measure proliferation, cytotoxicity, cell number and even apoptosis.
  • Kits include standards and controls to calibrate and standardize the assay.
  • Validated signal detection readout according to FDA Bioanalytical Method Guidelines.
  • Allows results to be compared over time.
  • Results usually in 4 to 5 days depending on species and cell type.
  • Designed for multiplexing with other assay using the same sample.
  • Simple, time efficient and cost effective.

Principle of ATP Bioluminescence 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 instrument and the ATP standard is used to standardize the assay. The values obtained provide the measurement assurance parameters that allow you, the user, to ensure that the results obtained can be trusted.

An example of an ATP standard curve and control results are shown in the diagram below and actual values for the kit being used are given in the Technical Manual. If the values obtained are within the ranges given in the Technical Manual, the user can process the samples knowing that the results will be trustworthy.
