Table 2 The pKa values and micro/macroscopic binding constants for the MC-dsRNA interaction. The pKa values and micro/macroscopic binding constants calculated in the experiments. From these values, the molar ratio of the binding species for MCH+ to MC was observed to be 90:10. The schematic shows the binding and protonation occurring due to interaction with dsRNAs
