In vitro test system

Details on the study design:
Test item
The test item was tested at 12 concentrations according to a geometric progression of ratio 2 from 0.2 µg/ml to 400 µg/ml.

Reference item
Negative control: 6 wells of solvent control (1% DMSO in treatment medium) with cells and 1 well of solvent control without cell by culture plate.
Positive control: 5 concentrations of cinnamaldehyde on each culture plate. The concentration varies from 4 to 64 µM according to a geometric progression of ratio 2.

The study was composed of two independent repetitions. For each repetition the test item and the reference items were replicated on three independent plates for the measurement of induction and two plates for the measurement of cytotoxicity. Each repetition was performed on a different day with fresh stock solution.
