The diffusion coefficients for two proteins differ by a factor
of 2, but the two proteins exhibit the exact same capillary
electrophoresis retention (or migration) times. How do they differ?
Can you estimate this relative difference? Would you expect these
proteins to sediment at different rates in an analytical
centrifuge? If so, what would the relative protein sedimentation
velocities be? HINT: You can assume the proteins are spherical in
shape.
