Biophysical characterization of MERS-CoV NTD+. (a) Binding of RNA to MERS-CoV NTD+ assessed by fluorescence polarization. 3′-Cy5-labelled RNA was incubated with various concentrations of NTD+. (b) MALLS/UV/refractometry/SEC analysis of NTD+. The right y axis represents the OD280 nm and the left y axis represents the molar mass in g mol−1 (Da). The absorption peak is shown as a noncontinuous line, with the continuous trace indicating the molar mass. The value of the measured mass at the volume corresponding to the top of the peak is reported. |
