[Standardization of indirect immunofluorescence for detection of autoantibodies (author's transl)].

Seven laboratories made a chessboard titration with a serum containing antimitochondrial antibodies and two conjugates labeled with fluorescein isothiocyanate. The variation of the plateau titer and the titer of the serum as well as the plateau-end point was slight with the exception of one case. The standardization of indirect immunofluorescence needs a close contact between the laboratories, the availability of reference sera and conjugates, and similar microscopic equipment.

[The quantitative immunochemical determination of specific antibodies against Candida albicans within the scope of immunological testing in the malignant melanoma (author's transl)].

Precipitating antibodies against a polysaccharide antigen from Candida albicans were in the human serum determined quantitatively by the aid of a reversed radial immunodiffusion technique. The gel, therewith, contained the antigens, whilst into the gel's punching holes the serum specimens and the calibrated standards were filled in. Amplifying examinations of the course in patients suffering from malignant melanoma, the findings of the methods used hitherto were compared within the scope of an immunological status (in vivo-skin testing by dinitrochlorobenzene, Candida antigen, trichophytin, and tuberculin, precipitation test after Ouchterlony, immunofluorescence-optical evidence of Candida antibodies as well as determination of the Candida antibodies. In contrast to the hitherto available qualitative or semi-quantitative methods evidencing humoral antibodies, we consider the feasibility of simply workable quantitative determinations of antibodies to be an enrichment of the scale of methods. The reversed Mancini technique, simultaneously, is appropriate to determine specific antibodies against other diagnostically relevant antigens, so far as precipitating antigen/antibody complexes are formed. Therewith, commercially available testing kits could favour the standardization.

[The quantitative immunochemical determination of Candida albicans-specific antibodies (author's transl)].

A diffusion method is described for quantitative determination of precipitating antibodies against polysaccharide antigen from Candida albicans. It is a reversed single radial immunodiffusion method with the antigen in the gel layer. As one parameter within an immunological testing programme antibody levels were estimated in serum samples from a patient suffering from malignant melanoma.
