The performance of Western blots (immunoblots) prepared with eight strains of Borrelia burgdorferi representing B. burgdorferi sensu stricto, B. garinii, and B. afzelii genospecies was tested with a panel of sera with various clinical presentations collected from eight geographic regions. European sera were generally more reactive to blots prepared with B. garinii or B. afzelii strain antigens,...

background: human cd34 is a transmembrane glycoprotein which is expressed in human hematopoietic stem cells (hscs) and the small- vessel endothelial cells of a variety of tissues. cd34 plays a critical role as a marker for diagnosis and classification of leukemia. anti cd34 antibodies are used for isolation and purification of hscs from bone marrow, peripheral blood and cord blood. objective: t...

A Western blot (immunoblot) assay was used to detect Campylobacter-specific immunoglobulin A in urine. Acute-phase urine samples from six children with Campylobacter diarrhea had titers ranging from 2 to 8. The highest titer was detected 4 days postonset. Campylobacter-specific immunoglobulin A was undetectable in the paired convalescent-phase specimens and urine samples from three control chil...

This report describes the detailed procedures for Western blot analysis using fluorescent antibodies. After electrophoresis and subsequent electroblotting, the fluorescent-labeled antibodies were visible upon ultraviolet illumination of the polyvinylidene fluoride (PVDF) membranes and could then be photographed to give an accurate record of the blots. Fluorescent labeling allows for photographi...
