Exploratory Research

Measured value Inhibition (%)
Animal species Others
Indication of the result The rate of decrease (%) of MTH1 enzyme activity against the control condition without test drug treatment is shown. Positive values indicate inhibitory effect on MTH1 enzyme activity. Negative values are replaced with 0.
Target diseases of assay Cancer
Assay level Cell-free
Protocol of assay 1) 1 μL of test drug, 44 μL of assay buffer, and 4 μL of diluted MTH1 were mixed in 96-well plate. The mixture was incubated for 15 min at 22 °C. 2) 100 μL of malachite green solution was added to wells. The mixture was incubated for 20 min at 22 °C. 3) MTH1 enzyme activity was measured by the absorbance at 620 nm.
