An antibody and its antigen are mixed in a solution to initiate the equilibrium reaction. At different time intervals, the amount of the free antibody in the reaction mixture is estimated by an indirect ELISA. The association rate constant was estimated by nonlinear regression against an equation introduced from the derivation of the mass balance of antigen-antibody interaction. This method can determine the association rate constant of antibodies with a dissociation rate constant up to 5 x 10(-3) s(-1). The association rate constant of a single-chain Fv (scFv) to its antigen, bovine pancreatic ribonuclease A (RNase A), determined by the present method agreed well with those determined by the fluorescence polarization method and surface plasmon resonance method. No significant difference in the association rate constant was found between the soluble anti-RNase A scFv and the same scFv displayed on a phage (5.65 +/- 0.54 x 10(4) M(-1) s(-1) and 5.96 +/- 0.56 x 10(4) M(-1) s(-1), respectively).
