Offering

  • Up to 4 cell lines selected from Horizon’s cell line collection (over 2,000 isogenic and 800 standard cell lines) can be tested
  • 10-point dose response curve (quadruplicates)
  • Up to 4 compounds of interest can be tested
  • 72 - 144 h* treatment time
  • Detection: Cell viability (ATPlite®)**
  • Deliverables: Interim report, dose response curves, IC50 values and raw data

*Treatment time is dependent on assumed MOA of the compounds **Cell viability assay can be multiplexed with single endpoint apoptosis assay. Please enquire for a custom assay, if this is of interest

Case study I: Response to MEK Inhibitor in Parental and KRAS Mutant Colon Cancer Cells

  • Parental and a panel of KRAS mutant SW48 colon cancer cell lines were treated with increasing concentrations of MEK inhibitor AZD6244 for 144 h.
  • Cell viability was detected with CellTiter-Glo.
  • Conclusions: SW48 KRAS mutant cells, especially KRAS G12A, G12C and G12D show resistance to AZD6244. Isogenic cell panels are a powerful and relevant tool for studying drug sensitivity/resistance in vitro, and can be used for predicting patient response based on tumor mutation status.

Case study II: Effect of Etopisode on Cell Viability and Apoptosis in Breast Cancer Cells

  • MDA-MB-231 breast cancer cells were treated with etoposide (0, 1, 3 and 10 mM) for 72 h.
  • Cells were incubated with CellTiter-Blue to detect viability and with Caspase-3/7 Glo to detect apoptosis (caspase-3/7 positive cells) in two sequential steps.
  • Conclusions: The addition of increasing concentrations of etoposide decreases cell viability and increases apoptosis.
