Analysis of purified Influenza PR8 virus by TEM (a and b) and FFF-MALS (c). TEM images show purified virions with different sizes and morphologies at (a) low magnification (scale bar = 500 nm) and (b) high magnification (scale bar = 100 nm), respectively. The average diameter of spherical virions estimated by TEM is 104 nm (radius – 52 nm). The average size of ovoid virions is 145 x 88 nm (radius 72 x 44nm). (c) The FFF-MALS fractogram of the virus shows the 90° light scattering signal (black line) during 31 to 61 min overlaid with RMS radius (red line).
