BACKGROUND Hepcidin, a key regulator of iron metabolism, binds to the iron transporter ferroportin to cause its degradation. In humans, hepcidin deficiency has been linked to hemochromatosis and iron overload, whereas increased concentrations have been reported in anemia of cancer and chronic disease. There is currently an unmet clinical need for a specific immunoassay with a low limit of quant...
Accurate and timely detection is vital for mitigation of tuber yield losses resulting from yam mosaic virus (YMV) infection on yam, a major food security crop in West Africa. The observation, from our previous studies, that the triple antibody sandwich enzyme-linked immunosorbent assay (TAS-ELISA), the most commonly used detection method for YMV, detected the virus in significantly less leaf sa...
Sandwich ELISA methods have been widely used for biomarker and pathogen detection because of their high specificity and sensitivity. However, the main drawbacks of this assay are the cost, the timeconsuming procedure for the isolation of antibodies and their poor stability. To overcome these restrictions, we herein fabricated artificial antibodies based on imprinting technology and developed a ...

OBJECTIVE To prepare monoclonal antibodies (MAb) and antisera specific for Escherichia coli (E. coli) O157, and to develop a sandwich enzyme-linked immunosorbent assay (ELISA) to detect E. coli O157 in foods. METHODS Spleen cells from BALB/c mice immunized with the somatic antigen of E. coli O157:H7 were fused with murine Sp2/0 myeloma cells. The hybridoma cell line specific for E. coli O157 ...
OBJECTIVE To establish a sandwich ELISA method for detecting vascular endothelial growth factor (VEGF) in sera of population and the patients with hepatocellular carcinoma (HCC). METHODS Full length and two truncated human VEGF cDNA sequences were amplified from a commercial plasmid pBLAST49-hVEGF by PCR and inserted into the prokaryotic-expression plasmid pET-32a or pGEX-2T. Various VEGF pro...
A novel double-antigen sandwich enzyme-linked immunosorbent assay (ELISA) was developed to measure rabies antibodies in dogs. In contrast to the 4 days required for detecting rabies antibody with conventional rabies antibody virus neutralization assays, this ELISA can be completed in hours, without using live virus, in routine laboratories.
