The scholars that highlight Ames test
limitations point to the fact that it is utilizing bacteria that is very different from human cell and therefore advocate for models using human or mammalian cells.
All chemicals and raw materials for the Ames test
were purchased from Molecular Technology Inc.
In contrast, the samples collected at points P3 and P4 showed a positive response to the Ames test
, and at point P4 a cytotoxic response was found at concentrations greater than 1200 [micro]g/plate.
Using the Ames test
, a compound is considered mutagenic if it reaches at least two-times the number of colonies of the spontaneous reversion.
Comparison of the Ames II and traditional Ames test
responses with respect to mutagenicity, strain specificities, need for metabolism and correlation with rodent carcinogenicity.
3) This is not, however, at the expense of its sensitivity, which is higher than that of the current gold standard Ames test
The same prepared extract of fresh feces and urine used for HPLC analysis was also assessed for mutagenicity by the Ames Test
using Salmonella typhimurium TA 98 (Ames et al.
In the Ames test
, not all substances that cause mutations in bacteria are found to cause cancer in animals or man.
The safety concern arises from the fact that ginger has been found to be teratogenic on the Ames test
The safety concern arises from the fact that ginger is found to be teratogenic on the Ames test
The Ames test
has become the standard by which many substances are measured for mutagenacity and carcinogenicity.
Commonly found in feces, 7-OHIQ was identified during the 1980s as a direct-acting mutagen in the Ames test
, a bacterial assay used to screen for potential carciongens.
