9-Aminoacridine positive control mutagen for Ames MPF and umuC assays. 1000 µg. Direct-acting frameshift mutagen. No S9 required. Research use only.

9-Aminoacridine is a direct-acting DNA intercalating agent causing frameshift mutations. It is the reference positive control for TA1537 and TA97a frameshift strains, where other direct-acting mutagens have reduced effectiveness. Confirms tester strain viability and assay sensitivity for these strains under non-metabolic activation conditions.

• Direct-acting frameshift mutagen — intercalating mechanism
