title: [A study of the single radial haemolysis optimization for complement haemolytic activity assay (author's transl)].
abstract: The experimental conditions for single radial haemolysis are analysed in order to optimize the haemolytic plate method for the assay of human total complement. The amount of haemolytic antibody used for sensitization of red cells, the concentration of sensitized sheep erythrocytes, the thickness of agarose layer, and the diameters of wells all exercise an influence on the area of haemolysis. The effects of these parameters are investigated with a view to obtaining the clearest reading and greatest sensitivity of the haemolytic activity plate method, and at the same time verifying the validity of the assay and the precision of the human serum haemolytic titres. This work reports the optimal experimental requirements with regard to the factors studied for minimizing the sources of error in complement haemolytic plate assay.
