Hyperimmune antisera to chromatographically purified hemoglobins F and A2 were produced in rabbits and made specific for the immunogen by adsorption with normal human hemoglobin A conjugated to cyanogen bromide-activated agarose. A radioimmunoassay was established that permitted identification and quantitation of each of these two minor hemoglobins in hemolysates containing other hemoglobin components. The quantities of hemoglobins A2 and/or F present in hemolysates of individuals with beta-thalassemia, sickle cell anemia, Hb-C disease, and other hematological disorders were determined immunochemically, and the results were commpared to values obtained by microcolumn chromatography for the measurement of Hb-A2 or with the alkali denaturation technique in quantitating Hb-F. The immunoassay procedure has a greater sensitivity than other commonly employed techniques and can detect as little as 0.05 mug of these hemoglobins.
