Primer-template | KD (nM)a |
---|---|
Control (T) | 182 ± 23 (270) |
U | 4.4 ± 1.3 (1.5) |
diFBz | 52 ± 8 |
FBzIm | 176 ± 19 |
The binding constants for the interaction of primer-templates (sequences given in the materials and methods) containing the bases indicated at the + 4 position were measured by direct titration (figure 5). The values (± standard deviation) are the averages found from four determinations. The values given in brackets for T and U were measured previously for analogous primer-templates using competitive titration (3).
