The BIOLINE Salmonella ELISA Test for Salmonella spp., which is a rapid, easy, and convenient assay was evaluated for use in detecting Salmonella in foods and feeds. Each food matrix or feed was artificially contaminated with low levels of Salmonella. Twenty different matrixes were studied and 20 different Salmonella strains from a broad variety of serogroups (B, C, D, E, F, G, H, I, M, O, P, a...

Contamination of cell cultures and sera used for animal virus propagation with mycoplasmas represents a serious problem, especially in virology. Therefore specific control measures must be used. To achieve this we introduced PCR for the detection of mycoplasma species in cell cultures and compared its results with ELISA and microbiological culture. Seven mycoplasma species which are the most co...

The present study describes how to process human postheparin plasma (PHP) containing hepatic triglyceride lipase (HTGL) that is utilized as a standard material of HTGL for the quantification of HTGL mass in human plasma. The optimal storage conditions for PHP were established by monitoring the stability of HTGL molecules in PHP as an antigen, which was stored in the liquid, frozen, or lyophiliz...

Recent cases of adulteration with melamine have led to the need for rapid and reliable screening methods. To meet this need, commercial enzyme-linked immunosorbent assay (ELISA) test kits for the detection of triazines were evaluated. The recently released Melamine Plate kit (Abraxis, Warminster, Pa.) displayed a limit of detection of 9 ng/ml for melamine in phosphate-buffered saline (PBS) and ...

There have recently been large outbreaks of Marburg hemorrhagic fever (MHF) caused by Marburgvirus (MARV) in the Democratic Republic of Congo and Angola. The development of reliable diagnostic systems for MHF is urgently needed. An antigen-capture enzyme-linked immunosorbent assay (Ag-capture ELISA) using either of the two monoclonal antibodies (2A7 and 2H6) produced by immunizing mice with rec...

Hepatocellular carcinoma (HCC) is a big problem in China where the Hepatitis B (HBV) infection patients are near to 120 million. Early screening and diagnosis is the key to reduce the incidence and mortality of HCC. Serum AFP detection is the main methods for diagnosis, recurrent monitoring and therapeutic evaluation of primary HCC. Hepatitis patients should detect the AFP at least once every s...

We analyzed the utility of a commercial NS1 antigen based ELISA (Panbio Dengue Early ELISA) for detection of dengue infection during the early acute phase and anti-Dengue IgM capture ELISA for detecting dengue infection in patients in dengue endemic settings. A total of 145 serum samples collected from febrile suspected dengue patients were tested for the presence of anti-dengue IgM antibody us...

Aim The aim of this study was to detect specific immunoglobulin (Ig) that could be used to determine monoclonal antibody in conjugate-making an effort for the indirect enzyme-linked immunosorbent assay (ELISA) diagnostic kit of toxocariasis in human. Materials and Methods The study was conducted to assess the Ig profile, based on ELISA-isotyping, in mice infected with second stage larvae eggs...

OBJECTIVE The aim was to test the performance of a commercial enzyme-linked immunosorbent assay (ELISA) kit for Candida mannan antigen for detecting Candida in oral rinse solutions. STUDY DESIGN Forty-eight oral rinse solutions (38 from patients and 10 from healthy volunteers) were available. Mannan antigen was measured using a commercial sandwich ELISA kit, Unimedi Candida. The result of the...
