Ten serogroups of Legionella pneumophila have now been described.' Although the direct fluorescent antibody technique is widely used to identify and serologically differentiate L pneumophila isolates,2 some cross reactivity between serogroups3 and some staining of non-legionella organisms with legionella antisera4 have been reporrea. Several simple alternatives to the direct fluorescent antibod...

Subcellular fractions from the cotyledon obtained by differential and density gradient centrifugation, and extracts of total proteins from both cotyledon and axial tissues were analyzed by diethylaminoethyl cellulose chromatography, zone electrophoresis, ultracentrifugation, immunodiffusion, and immunoelectrophoresis. Fractionation and characterization of proteins in subcellular organelles of t...

The patients examined in this study were the same cohort as in an earlier study of morphologic features2’ but with additional follow-up. Between March 1978 and February 1982, 100 patients were studied just prior to initial chemotherapy for MM; all were followed for at beast 3.5 years. Sufficient information was available on all patients to allow clinical staging, and bone marrow plasma cell LI ...

The year 2006 marks the 50th anniversary of the discovery of cellulose acetate (CA) electrophoresis by Joachim Kohn, a pathologist at Queen Mary's Hospital in Roehampton, London. During a career in pathology that began in 1950 and spanned 37 years, Kohn published more than 50 papers in clinical laboratory medicine. He was the first to report the use of CA microbiology filters as solid supports ...

By use of crossed immunoelectrophoresis techniques, respiratory syncytial (RS) virus-specific precipitates were produced between RS virus cellular antigen [solubilized in tris(hydroxymethyl)aminomethane-glycine buffer, pH 9] and antiserum raised in rabbits against semipurified RS virus. When these precipitates were employed as antigens for further immunizations in rabbits, antibodies (anti-RSV-...

The techniques of agar immunoelectrophoresis and agar double diffusion were applied to the study of the antigenicity of beta- and alpha(1)-lipoproteins separated by ultracentrifugation from normal human sera. The effects of delipidation were also investigated. It was shown that beta- and alpha(1)-lipoproteins are antigenically distinct. For each class of lipoprotein studied, a single antigenic ...

Human placental coated vesicles have been purified by a method involving sucrose-density-gradient centrifugation and treatment with wheat-germ agglutinin. These preparations were free of contamination by placental microvillus fragments. Crossed immunoelectrophoresis demonstrated that the coated vesicles contained a single serum protein, which was identified as transferrin. This transferrin was ...

Membranes of Micrococcus lysodeikticus possess antigens which are distinct from other cellular components such as cytoplasm, ribosomes, and cell walls. Only a few (two to three) components are found when dissociated membranes are examined by immunodiffusion and immunoelectrophoresis techniques. Membranes treated with 0.3% sodium dodecyl sulfate, 0.3% Triton X-100, trypsin, phospholipase A or C,...

A selection of 58 specimens with a monoclonal component identified by immunoelectrophoresis and/or immunofixation was analyzed with the immunosubtraction procedure on the Paragon 2000 capillary electrophoresis system. The capillary system detected 93% of the paraproteins and, using immunosubtraction, correctly identified 91% of the paraproteins. Paraproteins that were detected by immunofixation...

An analysis of the plasma proteins in the sol phase of sputum was carried out using quantitative cross immunoelectrophoresis. The average concentrations of nine plasma proteins were estimated in the sol phase of sputum specimens from 30 patients with chronic bronchitis and the values were compared with the concentrations of these proteins in saliva and serum specimens from the same group of pat...
