Triplex DNA pH Test

Sample preparation

ssDNA stocks: s1 (3'Cy5), S2, TFO (3'Cy3), S‑S1 (3'Cy5), S‑S2, and S‑TFO (3'Cy3) were each prepared at 1 mM in nuclease-free water.
Buffers: PBS adjusted to pH 5.5, 6.5, 7.0, 7.5, and 8.5; prepare 50 mL of each pH condition.

Incubation

For each pH condition, set up two groups (Group 1 and Group 2). To each reaction, first add 194 µL of the corresponding PBS buffer.

Group 1: add S1, S2, and TFO , 2 µL each.
Group 2: add S-S1, S-S2, and S-TFO , 2 µL each.
