solutions of 125i-labelled ligand-binding proteins ( lectins or monoclonal antibodies binding transferrin ) were incubated in these ligand-coated wells in the presence of various amounts of soluble ligands ( carbohydrates or transferrins ) : after equilibrium establishment the s/b values were determined and plotted against c and the values of k were obtained as the intercept of the plot with the abscissa .
