Ames test procedure

The Ames test uses several strains of the bacterium Salmonella typhimurium that carry mutations in genes involved in histidine synthesis i. e. it is an auxotrophic mutant, so that they require histidine for growth.

Its essential oil did not show any evidence of mutagenicity in the Ames test.

Ames Research Center also houses the world's largest wind tunnel, part of the National Full-Scale Aerodynamic Complex ( NFAC ): it is large enough to test full-sized planes, rather than scale models.

The 80 by 120 Foot Wind Tunnel at NASA Ames Research Center holds the distinction of being the largest wind tunnel test section in the world.

The Ames Arc Jet Complex has seven available test bays.

Ames was initially " terrified " at the prospect of taking the test, but he was advised by the KGB " to just relax.

According to Lunn and Sansone, Chemical degradation using bleach yields compounds which are mutagenic by the Ames test.

As NASA Administrator, Glennan presided over an organization that had absorbed the earlier National Advisory Committee for Aeronautics ( NACA ) intact ; its 8, 000 employees, an annual budget of US $ 100 million, and three major research laboratories — Langley Aeronautical Laboratory, Ames Aeronautical Laboratory, and Lewis Flight Propulsion Laboratory — and two small test facilities made up the core of the new NASA.

He is the inventor of the Ames test, a system for easily and cheaply testing the mutagenicity of compounds.

Bruce Ames developed the Ames test, described in series of papers in the 1970s, which is a cheap and convenient assay for mutagens and therefore potential carcinogens.

The Ames test uses the bacteria Salmonella typhimurium to test for mutagens.

The Ames test is widely used as an initial screen for possible carcinogens and has been used to identify potential carcinogens previously used in commercial products, and their identification led to some of those formulations, such as chemicals used in hair dye, being withdrawn from commercial use.

The ease with which Ames test allows widely-used chemicals to be identified as possible carcinogens made him an early hero of environmentalism.

As natural chemicals turned out to also be frequently mutagenic, he argued that environmental exposure to manufactured chemicals may be of limited relevance to human cancer, even when such chemicals are mutagenic in an Ames test and carcinogenic in rodent assays.

The tests involved the efforts of NASA Ames Research Center, Langley Research Center, Dryden Flight Research Center, the FAA, and General Electric, and required more than 4 years of work before the test occurred.

D., Bull returned to NASA and worked at the Ames Research Center from 1973 to 1985, where he conducted simulation and flight test research in advanced flight systems for both helicopters and fixed-wing aircraft.

Because of its virulence, the Ames strain is used by the United States as a " gold standard " for development of vaccines and testing their effectiveness, starting in the 1980s, after work on weaponizing the Vollum 1B strain ended and all weaponized stocks were destroyed after the end of the U. S. biological warfare program in 1969.

Subsequent work in Ames ' lab involved looking at an overview of what was mutagenic or carcinogenic, and to what degree.

Ames routinely assisted another CIA office that assessed Soviet embassy officials as potential intelligence assets.
