Abstract
FROM a knowledge of the diffusion constant and viscosity of protein solutions, it has been foundpossible to estimate molecular weight and shape. By combining W. Kuhn's equation1with arrhenius's equation2we obtain:where is the observed viscosity, 0 is viscosity of the dispersion medium, In is viscosity increment at infinite dilution, G is total volume of material in 1 c.c. of solution, b/a is the ratio of the long to short axis of a rod.
