In nine out of 11 patients with herpes zoster and neurological symptoms varicella-zoster antigen was demonstrated in CSF cells by indirect immunofluorescent staining. Cerebrospinal fluid cytology was in most cases highly suggestive of viral infection. This study demonstrates the value of both immunofluorescent staining on CSF cells and CSF cytology, as corroboration of an otherwise exclusively ...

Immunofluorescent staining of mammalian cells has provided a reliable approach for detection of specific antigen expression in situ. An advantage of fluorescent markers has been their applicability to automated, high-throughput cellular analysis by flow cytometry. Flow cytometry has thus become an integral component of clinical laboratory diagnostics, particularly in the areas of immunology and...

towelve calves of 4-10 months old with clinical signs suspected to bovine viral diarrhea virus (bvdv) infection were selected for this study. histopathologic sections were performed on formalin fixed paraffin-embded ear notch biopsies, mounted on poly-l-lysine coated slides and stained for bvdv by anti-bvdv monoclonal antibody labelled with fluorescein isothiocyanate. stained sections were exam...

Background: Monoclonal antibodies (mAbs) are essential tools for many molecular im-munology investigations, epitope mapping and molecular modelling, clinical laboratory di-agnostic tests and immunotherapy. Humoral immune response of immunized animals largely depends on the nature of antigen and the immunization technique. Polysaccharides and heavily-glycosylated proteins are very elusive target...

introduction: the implantation is a complex procedure that involves many molecules. one of these molecules is integrin specially &alphav;&beta3; which serves as receptor for components of extra cellular matrix to act as bridging molecules between the blastocyst and the endometrial surface during the implantation process. by blocking &alphav;&beta3; interactions, the implantation can be impaired...

We have measured thrombin-induced secretion of platelet factor 4 antigen (PF4) and simultaneously followed its intracellular translocation by immunofluorescence. In permeable resting platelets, speckled intracellular immunofluorescent staining for PF4 was observed. Addition of thrombin to washed platelets at 22 degrees C resulted in secretion of PF4 and formation of large (approximately 0.5 mic...

Factor-VIII-related antigen has previously been shown to be synthesized by vascular endothelial cells. Using both an immunofluorescent staining technique and electron microscopy, we have demonstrated the presence of factor-VIII-related antigen in human vascular subendothelium. This finding may have implications in the mechanism of platelet adhesion to deendothelialized blood vessel surfaces.
