Figure 6. Sequence-dependent effects of electrostatic force.

Figure 6

(a) Dependence of Keq on Vg, demonstrating higher values for the complementary compared to the SNP across all Vg values. Keq=1 defines a melting potential of Em=400.05 (±2.55) mV for the complementary target and Em=326.45 (±1.33) mV for the SNP; R2 values for the SNP and comp are 0.95 and 0.97, respectively. Error bars are calculated from five different 60-s intervals at each bias value. (b) An effective Tm curve showing the extrapolated temperatures for each hybridized fraction of both complementary and SNP target against their perspective nearest-neighbour models; and (c) calibration curves demonstrate the interchangeable effect of bias and temperature on reaction rates and further correlate each bias point with an effective temperature.
