Monoclonal Antibody-Based Capture Enzyme Immunoassays for Specific Serum Immunoglobulin G (IgG), IgA, and IgM Antibodies to Respiratory Syncytial Virus DEAN D. ERDMAN* AND LARRY J. ANDERSON Respiratory and Enterovirus Branch, Division of Viral and Rickettsial Diseases, Center for Infectious Diseases, Centers for Disease Control, 1600 Clifton Road, N.E., Atlanta, Georgia 30333 Received 17 May 1990/Accepted 24 September 1990
Monoclonal antibodies (MAbs) to the fusion protein (F), attachment protein (G), and nucleoprotein (N) of respiratory syncytial (RS) virus were evaluated for use as detector antibodies in immunoglobulin G (IgG), IgA, and IgM capture enzyme immunoassays. MAb assays were tested against assays using polyclonal antibodies (PAbs) with serum specimens from patients with and without evidence of recent RS virus infection. Assays developed with N MAbs were comparable to or better than PAb assays for detecting specific IgG and IgM antibodies but were somewhat less sensitive for IgA. F MAb assays were less sensitive for IgG and IgM antibodies but identified specific IgA in some specimens negative by N MAb assay. G MAb assays were insensitive for IgG and IgM antibodies but did detect about 50% of the IgA antibodies identified by the PAb assay. The basis for the low sensitivity of the G MAb assays is unclear, since many of these specimens were positive for IgG antibodies to G by Western immunoblot. The sensitivity of MAb assays varied with patient age: N MAb assays detected specific antibody responses to RS virus in all immunoglobulin classes in both adults and infants
