An antigen-capture enzyme-linked immunosorbent assay (ELISA) was developed to detect and measure isometamidium chloride in the plasma of Oncorhynchus tshawytscha and 0. mykiss. Isometamidium-ovalbunlin conjugate and anti-isometamidium antibodies were used to coat polystyrene plates. The peroxidase saturation technique was used to optirnize the coating antigen concentration; it demonstrated low ...

Deoxynivalenol (DON), one of the trichothecene mycotoxins, is a worldwide contaminant of wheat and barley, especially when infected by Fusarium graminearum, the causative agent of an epidemic wheat disease called Fusarium Head Blight. Because of the high risk of DON ingestion and the possibility of frequent exposure, it is important to develop a rapid and highly sensitive method for easy identi...

introduction: although the hepatitis e virus mostly causes a self-limited disease in general population, but the disease is more severe in pregnant women. hepatitis e accounts for about 10% of pregnancy associated deaths in southern asia. but the prevalence in iran is almost unclear, so this study is aimed to investigate the seroprevalence of anti-hev igg among a population of pregnant women in...

A 2-h indirect enzyme-linked immunosorbent assay (ELISA) using homogenate antigens of Rhizopus arrhizus and Rhizomucor pusillus was developed and compared with the existing immunodiffusion (ID) test for zygomycosis, using homogenate antigens of R. arrhizus. Utilizing 1:400 as a minimally positive ELISA titer, 33 of 43 proven cases of zygomycosis were diagnosed. The sensitivity of the ELISA was ...

A new type of immunoassay (enzyme-linked immunosorbent assay, ELISA) has been used for the detection of antibodies against Salmonella 0 antigens. The results show that ELISA is specific and highly sensitive. When compared with the Widal reaction, passive hemagglutination, and quantitative precipitation, ELISA was shown to be more sensitive. In addition, immunoglobulin G and immunoglobulin M ant...

Enzyme-linked immunosorbent assay (ELISA) has been served as both the workhorse and gold standard in immunoassay for its high specificity, sensitivity, accuracy, despite known shortcomings limitations....
