Abstract

Antigens determined by Epstein Barr virus (EBV) have been detected and quantitated in human lymphoblastoid cell culture lines by specific radioiodine-labeled antibody elution (RIE). The peak of specific elutable antibody has been shown to quantitatively increase with increasing doses of EBV 2-3 days after superinfection of susceptible lines. Increasing antibody concentrations on constant cell numbers produced a linear increase in elutable antibody binding specifically to the producer cells. Increasing cell numbers in the presence of a constant antibody concentration, likewise, produced a graded increase in the specific antibody eluted from the producer cells. Antigen suspensions prepared from frozen and thawed cells were used to complete with the antigens on the target cells for the antigen-combining sites of the labeled antibodies. Experiments were performed using suspensions from cells containing all the EBV-determined antigens for competition as well as limiting the competition to early antigen (EA).
