Relative binding affinities for polyamides
| R1,R2 | T·A | A·T | C·G | G·C | |
|---|---|---|---|---|---|

OH, H | 1.0 | 1.0 | <0.01 | <0.01 |
| F,H | 1.0 | 0.8 | <0.01 | <0.01 | |
| H, OH | 1.0 | 1.3 | 1.4 | 0.8 | |
| H, F | 1.0 | 0.6 | 0.6 | <0.01 |
Relative binding affinities are reported as ratios of binding affinities (Ka) as determined by DNase I footprinting titration experiments for polyamides targeting 5′-WGGWW-3′ Sites containing G·C at the hairpin position have relative affinities <0.01 (not shown).
