- RANGE-FINDING/SCREENING STUDIES:
A preliminary test was carried out to determine the toxicity of the test item using TA100 and WP2uvrA. The concentrations tested were 0, 0.15, 0.5, 1.5, 5, 15, 50, 150, 500, 1500 and 5000 µg/plate. In addition, a vehicle control (acetone) and a sterility control were run in parallel.
The test item was non-toxic to the strains of bacteria used (TA100 and WP2uvrA). - Remarks on result:
- other: all strains/cell types tested
