Ames II & MPF Test Services for Mutagenicity Testing


Our Ames test services include bacterial reverse mutation assays performed as fluctuation tests in a reduced liquid microplate format and exploiting a colorimetric read-out. Ames MPF and Ames II produce data with strong concordance to the classical Ames test but require considerably lower test item amounts. This makes them ideally suited to high-throughput screening projects.
