Immunfluorescenz-Untersuchungen bei verschiedenen Dermatosen

Investigations of skin cuts taken from positive potassium bichromate patch skin tests were carried out by means of the indirect fluorescence technique according to Weller and Coons. Punctiform indications of fluorescence were to be found due to ?-globulin-complexes. On this method the fluorescence is considered to be specifical, it is, however, pointed out that the antibody character of the ?-globulin-complexes located at these spots cannot be proved. The controltests carried out yielded negative results. The investigations are continued.
