title: Epstein-Barr virus early antigen titer by immunofluorescence in microplates. A new semi-automated method based on microtiter system.
abstract: For the titration of antibodies directed against Epstein-Barr Virus early antigen (EBV-EA) we describe a method in microplates with the Microtiter System (Cooke Engineering Co., Alexandria, Va). Using this technique, which allows rapid epidemiological investigations, we have titered anti-EBV-EA antibodies in different groups of patients and controls, and particularly in group which had recent contact with infectious mononucleosis. In this group the percentage of individuals having antibodies directed against the EBV-EA antigen was significantly higher than in the group of controls.
