Improved enzyme-linked immunosorbent assay (ELISA) methods have been developed for the determination of femtomole amounts of mycothiol (MSH), the main low-molecular-weight thiol in mycobacteria. The immunoassays utilize an affinity-purified rabbit polyclonal antibody that is highly specific for the pseudodisaccharide moiety of MSH. MSH was first biotinylated by the thiol-specific reagent 3-(N-m...
Introduction: Human immunodeficiency virus is the etiologic agent of immune system deficiency and the infected patients are susceptible to opportunistic infections and AIDS. Transmission of infection during blood transfusion and diagnosis of infection in hospitals and public health settings have steadily been a worldwide concern. Different techniques are now available for the diagnosis of HIV i...
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...
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...
OBJECTIVE To evaluate the performance characteristics of direct and capture ELISA for the detection of PR3-ANCA in Wegener's granulomatosis (WG) in international ANCA reference laboratories. METHODS Serum samples were derived from patients with histological and clinical diagnosis of WG (n = 60), rheumatoid arthritis (RA) (n = 30) and healthy controls (n = 30). Each of them was tested for the ...
Abrin, one of the most highly potent toxins in the world, is derived from the plant, Abrus precatorius. Because of its high toxicity, it poses potential bioterror risks. Therefore, a need exists for new reagents and technologies that would be able to rapidly detect abrin contamination as well as lead to new therapeutics. We report here a group of abrin-specific monoclonal antibodies (mAbs) that...
A new IgM capture enzyme linked immunosorbent assay (ELISA) was compared with the 19S(IgM) fluorescent treponemal antibody absorption (19S(IgM)FTA-ABS) test for detecting IgM antibodies to treponemes. Serum samples from 180 people, 109 with various stages of untreated syphilis, 45 with treated syphilis, and 26 non-infected, were investigated. In all diagnostic groups of syphilis the reactivity ...
One hundred and fifteen serum samples from healthy laboratory personnel and 50 consecutive samples from 19 patients with anamnestic clinical signs of toxoplasmosis were assayed by four laboratories for the presence of immunoglobulin M antibodies to Toxoplasma gondii by an indirect enzyme-linked immunosorbent assay (ELISA), an antibody capture assay with peroxidase-labeled toxoplasma antigen, an...
