[Exploration of humoral immunity in aspergillosis: value of enzyme linked immuno-electro-diffusion assay].

In order to increase the sensitivity of the method of immunoelectrodiffusion (I.E.D.) and to isolate the class of immunoglobulins implicated or involved in the Aspergillose antigen-antibody reaction, we supplemented the I.E.D. by combining or incorporating it with an enzymatic technique. By this method the immune complexes precipitated are taken up by antibodies conjugated to one enzyme and specific to the immunoglobulins of each class. This constitutes the technique of E.L.I.E.D.A. (enzyme-linked-immuno-electro-diffusion assay). The sensitivity and the specificity of the proposed method would allow us to follow the qualitative evolution of the aspergillar antibodies and would lend support to further arguments on the evolutionary character of the inflammatory response.
