Influenza serology has traditionally relied on techniques such as hemagglutination inhibition, microneutralization, and ELISA. These assays are complex, challenging to implement in a format allowing detection of several types of antibody-analyte interactions at once (multiplex), and troublesome to implement in the field. As an alternative, we have developed a hemagglutinin microarray on the Arr...
The use of diagnostic laboratory tests usually includes a comparison of the result obtained in a given patient to a reference range. The definition of this reference or “normal” range is a priori simple: one has to measure the analyte in a “normal” population using a reference method, and there you are! Unfortunately life is not that easy. Routine methods frequently provide results that are not...
Cold agglutinins are autoantibodies and are often present in the sera of healthy individuals. They assume importance when the thermal reactivity of these antibodies approaches body temperature. This communication describes a case of cold hemagglutinin disease with Mycoplasma pneumoniae infection detected during routine laboratory investigations. The patient was managed conservatively.
The intracellular pathway followed by the influenza virus hemagglutinin (HA) to the apical surface of Madin-Darby canine kidney cells was studied by radioimmunoassay, immunofluorescence, and immunoelectron microscopy. To synchronize the migration, we used a temperature-sensitive mutant of influenza WSN, ts61, which, at the nonpermissive temperature, 39.5 degrees C, exhibits a defect in the HA t...
Vaccination is the most effective prophylactic method for preventing influenza. Quantification of influenza vaccine antigens is critically important before the vaccine is used for human immunization. Currently the vaccine antigen quantification relies on hemagglutinin content quantification, the key antigenic component, by single radial immunodiffusion (SRID) assay. Due to the inherent disadvan...
Little was known about bioactive compounds from the hallucinogenic mushroom Boletus speciosus. In the present study, a hemagglutinin (BSH, B. speciosus hemagglutinin) was isolated from its fruiting bodies and enzymatic properties were also tested. The chromatographic procedure utilized comprised anion exchange chromatography on Q-Sepharose, cation exchange chromatography on CM-Cellulose, cation...
