Abstract
A new immunochromatographic assay was developed for serodiagnosis of tuberculosis based on the interaction of specific anti-Mycobacterium tuberculosis immunoglobulins that are present in the blood serum with a label-antigen conjugate followed by the binding of the resulting complex to the Staphylococcus aureus protein A immobilized on a test strip. Unlike the conventional technique, in which all immunoglobulins that are present in the sample react with a label-immunoglobulin-binding protein conjugate, the new technique eliminates the binding of blood serum immunoglobulins, which are non-specific to Mycobacterium tuberculosis, to the label, and then specific antibodies involved in the labeled complex bind to the immobilized antigen. The new assay was implemented using the recombinant 38-kDa (Rv0934) protein of M. tuberculosis as the antigen and colloidal gold as the label. It was experimentally shown that the new assay allows for an increase in the percentage of the detection of seropositive serum samples with low concentrations of specific antibodies against the causative agent of tuberculosis.
