  • Evaluated cytotoxicity endpoints.

Main Results:

  • Identified weaknesses in sensitivity and reproducibility of established cytotoxicity endpoints.
  • Demonstrated the effectiveness of bioluminescent ATP/ADP detection assays.
  • New kits provide a solution to existing problems in high-density cell-based assays.

Conclusions:

  • Bioluminescent ATP/ADP detection assays offer enhanced sensitivity and reproducibility for high-density cell-based cytotoxicity testing.
  • These novel kits address critical challenges faced by the pharmaceutical industry.
  • Improved assay performance facilitates more reliable drug discovery and development processes.
