Method Diffusion measurements were carried out in an 11ml quartz Tiselius cell in a Spinco model H electrophoresis-diffusion apparatus.
Comments Measured at a virus concentration of 0.42 per cent. Extrapolation to infinite time gives a diffusion coefficient of 8.62x10^-8 cm^2/sec. This value was corrected to that expected in water at 20°C. Thus D20,W=1.55x10^-7 Cm^2/sec.
