Fungal mycelium extracts were subjected to gel electrophoresis and Western blot analysis with various lectins and polyclonal antisera. These techniques succeeded in identifying bands specific to pathogenic Aphanomyces strains from fish affected by epizootic ulcerative syndrome, redspot disease and mycotic granulomatosis when compared to various other Oomycete fungi. It is concluded that these i...

Western blot analysis is a widely used technique for protein immunodetection. Its current format, however is unsuitable for multiplex detection of proteins, primarily due to intrinsic limitations of standard organic dyes employed as probes. Quantum dot (QD) semiconductor nanoparticles exhibit significant advantages over organic dyes, including their broad absorption bands, narrow, tunable, and ...

In order to evaluate the presence of specific IgG antibodies to Borrelia burgdorferi in patients with clinical manifestations associated with Lyme borreliosis in Cali, Colombia, 20 serum samples from patients with dermatologic signs, one cerebrospinal fluid (CSF) sample from a patient with chronic neurologic and arthritic manifestations, and twelve serum samples from individuals without clinica...

In order to evaluate the use of a Western blot methodology for the diagnosis of infectious bursal disease virus (IBDV) infection, chickens were experimentally infected with IBDV strains and tested for the presence of viral antigens and antibodies by a blocking Western blot test (bWB). The viral proteins obtained from the bursa of Fabricius (BF) were transferred to a nitrocellulose membrane afte...

Evaluation of a western blot serum test for the diagnosis of Mycobacterium tuberculosis infection. E. Rovatti, M.P. Corradi, M. Amicosante, P.L. Tartoni, W. Panini, A. Ancora, A.M. Cenci, L. Zucchi, L. Monno, G. Angarano, C. Saltini. ERS Journals Ltd 1996. ABSTRACT: This study was designed to evaluate the possibility of monitoring Mycobacterium tuberculosis infection using a serological assay....

Accurate and reproducible quantifi cation of proteins on Western blots across a wide linear range is desirable, but diffi cult to achieve. Chemiluminescent detection is subject to enzyme/substrate kinetics that may affect performance, and use of antibodies labeled with visible fl uorophores has not provided the necessary sensitivity for practical use. In this study, we investigated the use of a...

Nora virus is a single stranded RNA picorna-like virus with four open reading frames (ORFs). The coding potentials of the ORFs are not fully characterized, but ORF3 and ORF4 are believed to encode the capsid proteins (VP3, VP4a, VP4b, and VP4c) comprising the virion. To determine the polypeptide composition of Nora virus virions, polypeptides from purified virus were compared to polypeptides de...

Paracoccidioidomycosis (PCM) is a serious infectious disease that progresses toward death if untreated. Its confirmatory diagnosis is made by the detection of the fungus Paracoccidioides brasiliensis in a direct mycological examination or by histopathology. However, these techniques are of low sensitivity. Serological tests seem to be more promising. The objective of this study was to test West...

Western blotting is a technique that has been in practice for more than three decades that began as a means of detecting a protein target in a complex sample. Although there have been significant advances in both the imaging and reagent technologies to improve sensitivity, dynamic range of detection, and the applicability of multiplexed target detection, the basic technique has remained essenti...
