Figure S3. Dose-response curves of revertant Salmonella Typhimurium strain TA1535 colonies following treatment with SA in the absence of S9 mix (a), or with 2AA in the presence of S9 mix (b). Individual dose-response curves were generated using results produced by each participating laboratory in 2016 (different colors indicate different laboratories). The doses tested were 0.125, 0.25, and 0.5 μg/plate for SA, and 0.5, 1.0, and 2.0 μg/plate for 2AA. (ODP 411 kb)
