Enzyme-linked immunosorbent assay for detection of antibodies to Epstein-Barr virus antigens.

Enzyme-Linked Immunosorbent Assay (ELISA) was standardized for measurement of antibody activity of reference human and baboon (Papio hamadryas) sera to soluble Epstein-Barr virus (EBV) antigens. A comparison with the immunofluorescent (IF) method showed that ELISA detects antibody specifically and sensitivity. In ELISA, Herpesvirus Papio (HVP) nuclear antigen (HUPNA) positive baboon serum reacted with EBV nuclear antigen (EBNA), as a further indication of the antigenic similarity between HVP and EBV. Forty-two baboon sera were tested with EBV antigens in both ELISA and IF test. The results showed an agreement between the two methods and also that by the use of EBV antigens, ELISA measures anti-HVP activity of baboon sera. ELISA did not reveal significant difference in antibody activity of 23 baboons with lymphoma and that of 24 healthy baboons. Results provide further data that ELISA can be used effectively in the field of EBV serology.
