Protokoll
anti-VZV IgM assay is a solid-phase immunoanalytical test. The polystyrene strips are coated with a native antigen. Anti-VZV antibodies from serum samples bind to the immobilized antigens. The other serum antibodies do not bind and are washed away, those that formed complexes with the antigens are later on recognised by animal anti-human IgM antibodies labelled with horseradish peroxidase. The presence of the labelled antibodies is revealed by an enzymatic reaction with a chromogenic substrate. Negative sera do not react and the mild change in colour, if present, may be attributed to the reaction background.
