CONSISE - The consortium for the Standardization of Influenza Seroepidemiology - is a global partnership to develop influenza investigation protocols and standardize seroepidemiology to inform health policy. This international partnership was formed in 2011 and was created out of a need, identified during the 2009 H1N1 pandemic, for timely seroepidemiological data to better estimate pandemic vi...

Five different immunoassay formats were examined for their ability to detect a minute quantity of prey remains in predator guts. The convergent lady beetle, Hippodamia convergens Guérin-Meneville, that had consumed either one or five pink bollworm, Pectinophora gossypiella (Saunders), eggs was evaluated by the following immunoassays: three variations of enzyme-linked immunosorbent assay (ELISA)...

The diagnosis of congenital cytomegalovirus (CMV) infection is often accomplished by the detection of circulating antibody directed against CMV. We devised a method for measuring CMV-specific immunoglobulin M (IgM) based on the isolation of IgM antibody by reaction with a solid phase coated with antihuman IgM. The determination of IgM antibody specific for CMV was accomplished by the subsequent...

COMPARISON OF ENZYME IMMUNOASSAYS FOR THE DIAGNOSIS OF BOVINE BRUCELLOSIS. The indirect enzyme immunoassay for measurement of bovine antibody to Brucella abortus was tested on 15,716 Canadian sera to assess the specificity. These sera were also tested by the buffered plate antigen test. Two ELISA formats were used for assessment of data: the targeting procedure using a positive control serum al...

Immunoassays have been widely used as the standard technology for quantitative detection of analyte concentrations in the fields of medicine, environmental science, and food science. Immunoassays such as enzyme-linked immunosorbent assays (ELISA), fluorescence immunoassays (FIA), electrochemical immunoassay (EIA), immunoagglutination assays (IAA) and radioimmunoassays (RIA) are the most commonl...

A rapid enzyme-linked immunosorbent assay (ELISA) test (microwell plate) and a membrane-based colloidal gold immunoassay in flow-through and lateral-flow formats for the rapid detection of fumonisin B1 (FB1) were developed. The rapid microwell assay can be completed within 20 min with the detection limit of 0.5 +/- 0.2 microg/L. Membrane-based colloidal gold immunoassays had a visual detection ...
