Nitrofluorenas – teigiamieji kontroliniai pavyzdžiai Ames MPF, umuC tyrimams (20 mikrogramų)

2-Nitrofluorene positive control mutagen for Ames MPF and umuC assays. 20 µg. Direct-acting frameshift mutagen for TA98. No S9 required. Research use only.

2-Nitrofluorene is a direct-acting nitroarene activated by the nitroreductase enzyme present in TA98. It induces frameshift mutations without S9 metabolic activation, serving as a direct-acting positive control specifically for the TA98 strain. Confirms TA98 strain responsiveness and assay sensitivity under non-metabolic conditions.
