GLP Ames 24-Well Agar Test Services

SERVICE INFORMATION

Using a microwell format, the GLP Ames test, specifically the Ames 24-well Agar test, provides predictivity of the OECD 471 Ames study in comparable conditions, using just 5% of the test item. It is also conducted in solid agar. This makes the 24-well version of the Ames test highly amenable to screening, with TA98 & TA100 providing coverage for most known mutagenic substances.
