The AK421 antibody recognizes the Dictyostelium mitochondrial porin by Western blot

Understanding the Western Blot

Inquiries about various issues relating to Western blot (WB) testing are frequently posted to the Lyme disease discussion groups on the Internet. Among the most commonly asked questions are: What laboratory techniques are used to carry out the assay? What exactly is being measured? What is a “band”? How are the results interpreted? What are the CDC criteria for a “positive” test? Although some ...

Validation of western blot for Histoplasma capsulatum antibody detection assay

BACKGROUND Histoplasmosis is worldwide systemic mycoses caused by the dimorphic fungus Histoplasma capsulatum. The isolation and identification of H. capsulatum in culture is the reference test for histoplasmosis diagnosis confirmation. However, in the absence of it, serology has been used as a presumptive diagnosis through antibody and antigen detection. The purpose of the present study was to...

The fallibility of HIV western blot.

Analysis of antibody responses by commercial western blot assay in horses with alveolar echinococcosis.

Commercial western blot (WB) assay was used to detect serum antibodies specific to Echinococcus multilocularis in 23 horses in which infection was confirmed by postmortem inspection at a slaughterhouse. Livers contained from 1 to >20 nodular lesions; foci diameter ranged from 1 to 25 mm. Antibody tests of serum from all 23 animals were negative for antigen bands at 7, 16, 18, and 26-28 kDa, whi...

Antibody responses to Borrelia burgdorferi detected by western blot vary geographically in Canada

Lyme disease is emerging in eastern and central Canada, and most cases are diagnosed using the two-tier serological test (Enzyme Immuno Assay [EIA] followed by Western blot [WB]). Simplification of this algorithm would be advantageous unless it impacts test performance. In this study, accuracy of individual proteins of the IgG WB algorithm in predicting the overall test result in samples from C...
