the DNA reporter was measured using a CLARIOstar Plus microplate reader
(BMG LABTECH). At the end of the definitive screening design runs,
20 μL reaction volume was mixed with 80 μL water in each
well of a black and clear flat-bottom 96-well microplate (Greiner).
For sensitivity tests, 1 μL reaction samples were taken and
measured every 10 min. To measure the fluorescent intensity of 6-carboxyfluorescein
(6-FAM), the excitation wavelength was set to 495 nm and the emission
wavelength was set to 520 nm with an 8 nm bandwidth for both. An enhanced
dynamic range (EDR) was used for fluorescence gain. To visually observe
the test tubes, UV light (BioDoc-It, UVP) and a blue-LED transilluminator
(Safe Imager 2.0, Thermo Fisher Scientific) were used.
