Dr bruce ames develops test to detect mutagens and carcinogens

dr bruce ames develops test to detect mutagens and carcinogens It was first developed by dr bruce ames in 1971, and gave researchers a faster and less expensive way to get results “this assay uses a set of histidine-requiring strains of the bacterium salmonella typhimurium to detect mutations induced by a test agent.

The ames test uses salmonella bacteria as guinea pigs to test whether a chemical is a mutagen let's see how this works to do the ames test, you start off with a mutant strain of salmonella bacteria. The scientist, dr bruce ames, of the university of california at berkeley, was the developer of the most widely used rapid laboratory test, the so-called ''ames test,'' for detecting the probable . The procedure you will perform was developed by bruce ames in order to though not all mutagens identified by the ames test turn out to be potent carcinogens, the .
