(a) SAXS from 9.59 mg ml−1 CPMV suspension in 0.007 M K3PO4 buffer (sample A) averaged over 100000 frames collected continuously within 1.92 s. The result was further averaged from 1000 repeated measurements to improve the statistics. (b) Azimuthal average of (a) for sample A (red circles), 9.59 mg ml−1 CPMV in 0.007 M K3PO4 and 0.5 M NaCl (sample B, yellow triangle), 9.59 mg ml−1 CPMV in 0.007 M K3PO4 and 0.5 M (NH4)2SO4 (sample C, green square). The solid blue line is the form factor calculated from spherical particles with a Gaussian distribution of the radius (average = 13.0 nm, standard deviation = 1.2 nm). |
