TABLE 1.
Cry1Ab kinetic parameters and equilibrium dissociation constants from Cry1Ab-susceptible and -resistant European corn borer, Ostrinia nubilalis, strains using real-time analysis (Biacore 2000)a
| Strain | kon (M−1 s−1) (103) | koff (s−1) (10−4) | Kd (nM) |
|---|---|---|---|
| Europe-S | 10.7 ± 0.3 a | 3.7 ± 0.4 a | 35 ± 3 a |
| Europe-R | 9.7 ± 0.3 b | 5.9 ± 0.5 a | 61 ± 6 b |
| RSTT-R | 10.03 ± 0.04 b | 9.5 ± 1.1 b | 94 ± 11 c |
