Begin by pipetting G4-TBA, single-stranded TBA, and double-stranded TBA solutions into three different tubes for folding. Heat the samples to 95 degrees Celsius for five minutes. Let them cool slowly to room temperature.
Once the tubes have cooled to room temperature, centrifuge the tubes. Next, organize three sets each of seven empty autoclaved 0.5-milliliter tubes. Add three microliters of ultrapure water into each tube.
Pipette five microliters of the folded nucleic acid constructs into each tube of the set. Next, add two microliters of either 25 or 250-micromolar B-CEP1 to obtain the final probe concentration of five and 50 micromolar respectively. To the three control tubes, add ultrapure water instead of the compound and incubate all the samples at 37 degrees Celsius.
Stop the reaction by placing the tubes at 20 degrees Celsius, then dry the samples in a vacuum centrifuge.
