Method Description

Antibody to parvovirus B19 is detected by a sandwich enzyme immunoassay for the detection of IgG or IgM class antibodies in serum or plasma. Specific parvovirus B19 antibodies in specimens bind to antigen-coated microtiter wells. Following a wash step, peroxidase-labeled rabbit-antihuman IgG is added that binds to parvovirus antibody. The antigen-antibody complex is detected by the addition of substrate, which turns blue in the presence of the enzyme peroxidase.(Anderson LJ, Tsou R, Parker RA, et al: Detection of antibodies and antigens of human parvovirus B19 by enzyme-linked immunosorbent assay.
