The x-axis for each of the curves from Figure 2 was transformed from radius to s* by the following relationship to compensate for the different times of sedimentation: This transforms the x-axis from the stationary reference frame of the ultracentrifuge cell to the moving reference frame of sedimentation.
where w is the angular velocity of the rotor
t is the sedimentation time
r is the radius, and rm is the radius of the meniscus.
