Interaction of the open MC form with dsRNAs. a, b The absorbance spectra before and after the addition of 200 μM of poly AU (a) or poly GC (b) to 12 μM of SP. c, d Change in the absorbance spectra as an increasing amount of poly AU (c) or poly GC (d) is added to 12 μM of MC in 9 mM Na + ions buffer at pH 7. Concentration is increased from 0 to ~ 600 μM. e, f Change in the absorbance spectra of MC upon addition of an increased amount of poly AU (e) or poly GC (f) to 12 μM of MC at pH 7 in TDW. Concentration is increased from 0 to~ 450 μM
