gp42 is not necessary for EBV-induced epithelial cell fusion. Various combinations of EBV glycoproteins were transfected into CHO-K1 cells as indicated. The cells were mixed 1:1 with either Daudi, HEK-293-P, or HeLa cells, and, 24 h later, the cells were harvested and relative luciferase activity was measured. These data depict one representative experiment of a total of five experiments.
