    Description / Table of Contents: Zusammenfassung Durch sukzessive Reinigungsschritte in der präparativen Ultrazentrifuge (Sedimentation auf Saccharosekissen, Gleichgewichtszentrifugation im CsCl-Dichtegradienten, zonale Zentrifugation im Saccharosegradienten) gelingt es, humanproteinfreie Australia-SH-Antigen-positive Präparate herzustellen. Mit diesen Präparaten wurden Meerschweinchen immunisiert, die daraufhin Antikörper bildeten, die ohne Absorption sowohl im Agar-Gel-Immunodiffusionstest als auch in der für den Nachweis des Australia-SH-Antigens empfindlicheren Komplementbindungsreaktion verwendet werden konnten. Antikörper gegen menschliche Serumproteine waren nicht nachweisbar. Die Titerhöhe entspricht den durchschnittlichen Titern unserer menschlichen Antiseren.
    Notes: Summary Using a three step purification method in the preparative ultra-centrifuge (sedimentation on a sucrose cushion, equilibrium centrifugation in CsCl density gradients, zonal centrifugation in sucrose gradients) it is possible to obtain HAA positive fractions free of human serum protein. Guinea pigs immunized with these fractions produced a monospecific antibody which could be used without any absorption in the immunodiffusion as well as in the complement fixation test, the latter being more sensitive for detection of HAA. The antisera did not show any reaction with pooled human HAA negative sera. The titers are as high as the average ones estimated for our human antisera.
