Gate Anneals
Room Temperature Annealing
- Mix gate and output in a 1.2:1 ratio in a tube.
- Cover the tube in foil, if you didn't use an opaque/black tube.
- Leave the tube on a bench top overnight.
Annealing With Heatblock
- Preheat the heat block to 95°C, add water to the well you will be using.
- Put a piece of styrofoam (covered with foil) on the heat block. Make sure the temperature is still at 95°C, and doesn't jump
- Mix gate and output in a 1.2:1 ratio in a tube, put it in the heat block.
- Cover again with the styrofoam, set the heat block to RT.
- 5. Wait until the block cools. It will probably not reach RT, but will be at around 30°C after a few hours. Turn the block off completely and wait for a bit (1h).
N.B. It may be possible to anneal using a lower maximum temperature (say, 80°C), as long as it is higher than the melting temperature of the oligos.

Plate Reader Studies
Kinetic Studies
- Prepare wells: 100 µL 1X TAE, 12.5 mM Mg2+ buffer; 10 nM 100 µL RNA-ROX (gate); 10 nM 100 µL gate:output complex; 10 nM 100 µL gate:output complex.
- Measure fluorescence of all wells for 1 minute (5 seconds between measurements).
- Add 1 µL of the buffer to the buffer and gate wells. Add 1 µl of 1 µM input S6 to the first gate:output well; add 1 µL of 1 µM input S1 to the second gate:output well. Note: Mix well by pipetting into the well, after adding input shake the plate by doing a sort of swirling motion in a plane. If possible, set the plate reader to do this for you for 3 seconds with a 1 second rest time.
- Measure fluorescence of all wells for 10 minutes (5 seconds between measurements).
