Estimation of Heterogeneity from Diffusion Measurements
IN order to estimate heterogeneity of molecular weights (in proteins) from diffusion measurements, Charlwood 1 uses the relation where D i is the diffusion constant for the weight fraction α i (in the sense of probability density), and σ the standard deviation of D i . In terms of the absolute momen...

uses the relation
where
D
i
is the diffusion constant for the weight fraction α
i
(in the sense of probability density), and σ the standard deviation of
D
i
. In terms of the absolute moments,
of the refractive index gradient curve this becomes
