AMES screening is performed with two tester strains of Salmonella; TA 98 and TA 100 (mini AMES). As an in vivo toxicity endpoint, the acute lung inflammogenicity in a rat instillation model was compared with the in vitro toxicity endpoints comprising cytotoxicity, pro-inflammatory cytokine expression, or haemolytic potential. The positive control induced a high degree of toxicity in all in vitro tests performed, indicating that the toxicity observed in the direct contact assay was due to in situ extraction of toxic components. Newly generated in vitro toxicity test methods can easily reveal the antitumor activity of large numbers of compounds with accuracy. First Published 1995. Both XF and PXF displayed severe acute toxicity in 240 times of human highest dosage; however, this dosage was too extreme in the clinical usage. Certainly, stronger associations between in vivo toxicities and in vitro patterns or signatures remain to be established. Growth in such early safety assessment initiatives has driven the need for more reliable and cost-effective high throughput in vitro toxicity assays capable of predicting toxic liabilities prior to investment in more costly pre-clinical and clinical trials. Colloquially called "test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes, and microtiter plates. Assessment can be subdivided into proliferation assay, apoptosis assay, necrosis assay, oxidative stress assay and DNA damage assays.
