It was shown that a reversible endothermic association of TMV protein subunits (A protein) can take place at pH values below the isoelectric point as well as at pH 6.5. The polymerization occurring below the isoelectric point was found to be more complex than that at pH 6.5 probably because products other than the usual TMV-like rods were formed in addition to those rods and also because side-to-side...
It has been shown that when concentration of solute is expressed as amount per unit volume of gel—solvent—solute system, Fick's laws for diffusion in a gel take the same form as for diffusion in solvent alone, except that the usual coefficient must be replaced by a new coefficient, D′, equal to D(1 - αφ)/(1 - φ), where φ is the effective volume fraction of the gel substance and α is a coefficient...
