RIA system programming by means of kinetic parameters.
Insulin-125I antibody reaction was optimized by physical-chemical parameters. After the activation energies Ea and Ed for association and dissociation, respectively were calculated from the experimental data, the theoretical values of the reaction rate constants ka and kd were determined as well as equilibrium constants K. By means of the empirical formulae, the approximate incubation time for the RIA kit and maximal percent of insulin-125I binding to antibody (%B) in relation to temperature were computed. The proposed method may be applied to the new antigen-binder systems preparation (new antibodies, shortening of the incubation time, temperature changes, influence of different ions and kind of buffer).
