The total 476 sera were examined by a routine electrophoresis and further by the use of immunoelectrophoresis. 1) Among the 42 broad banded hypergammaglobulinemics, neither M-components nor a lack of a.ny class of immunoglobulin was detected. 2 ) Out of the 23 hypogammaglobulinemics, 3 cases of dysgammaglobulinemia were found only after the immunoelectrophoresis. 3 ) All of the 51 cases with a ...

Countercurrent immunoelectrophoresis was used to assay bloodmeals to determine the hostspecificity of Anopheles culicifarics species-A and B, collected from areas in Delhi, Uttar piadesh and Bihar. Results indicated the-predominantly zoophagic nature of species A and B with " r.t"tiullv higher degree of anthropophagy for species A. Furth-er, the human blood index was found to be relatei to the ...

We describe for the first time a multi-antisera applicator to be used on cellulose acetate membranes with immunoelectrophoresis on a solid support. The new procedure overcomes previous shortcomings of immunoelectrophoresis on cellulose acetate membranes and permits rapid analyses of 11 samples on single “standard”-size membranes with a substantialsaving in antisera, celluloseacetate membranes, ...

The five mycobacteria Mycobacterium lepraemurium, M. leprae, M. bovis BCG, M. smegmatis, and M. intracellulare were studied. Catalase and peroxidase activities were demonstrated in polyacrylamide and crossed immunoelectrophoresis gels for M. lepraemurium, M. intracellulare, and BCG, but not for M. leprae. Peroxidase and catalase activities were associated with the same precipitate line in cross...
