Role of pentamer complex-specific and IgG subclass 3 antibodies in HCMV hyperimmunoglobulin and standard intravenous IgG preparations

ConclusionVia specific antibody depletion, we could demonstrate that pentameric complex-specific antibodies are present in HIG and bind to the recombinant PC resulting in a highly significant reduction of NT-capacity compared to the UL130 TAN-and SWS-peptides. We could not confirm the functional role of IgG subclass 3 neutralizing antibodies in IgG-preparations. (Source: Medical Microbiology and Immunology)
