  • Title: [Determination of rate constants of antigen-antibody reaction. A theory].
    Author: Bobrovnik SA, Starodub NF.
    Journal: Biokhimiia; 1988 May; 53(5):826-31. PubMed ID: 3167124.
    Abstract:
    A new method of determination of rate constants for antigen-antibody interactions is proposed. This method is based on a solid phase immunoenzymatic analysis of the dynamics of elution of immobilized antigen-bound antibodies in the presence of a free antigen. The kinetics of this process is described by a system of differential equations, whose solution results in expression defining the dynamics of antibody interaction with immobilized and free antigens. Simple formulas were derived for the calculation of the rate and equilibrium constants for the antibody-antigen reaction on the basis of experimental kinetic curves. The use of theoretical kinetic curves for antibody elution showed that these formulas reflect with a high degree of accuracy the kinetic properties of the reaction under study.
