Method Primary source [4] summary: "When an antibody combines with a hemeprotein antigen the fluorescence of the tryptophan residues of the antibody is partially quenched. With fluorescence quenching as an indicator, the stoichiometries and kinetics of the reactions of antihemoglobin A antibodies with various hemoglobins and the reactions of antihuman cytochrome c antibodies with various cytochromes c have been studied."
