Analysis of Reversibly Interacting Systems by Differential Boundaries in Electrophoretic and Sedimentation Experiments

Naturevolume 199page688 (1963) | Download Citation



DIFFERENTIAL boundaries, which can be formed in Tiselius electrophoresis cells or in special ultracentrifuge cells1,2 between solutions differing slightly in composition, may prove to have distinct advantages over ordinary boundaries for the study of rapidly reversible interacting systems. This possibility is being explored theoretically by considering model systems in which it is assumed that the transport of species occurs in rectangular cells under a uniform force field, that the mobilities or sedimentation coefficients of reacting species are independent of concentration3 and that reaction is governed by the simple form of the law of mass action.
