Representative microphotographs showing early antigen expression in Raji cells induced with or without 3-ABA. EBV lytic cycle was induced as described in the Methods in the absence (b), or in the presence (c) of 3 mM 3-ABA. Latently infected Raji cells exposed or not to 3-ABA (a) were used as control. At the indicated times (24, 48 and 72 hours) cells were collected and stained with FITC-labeled EA antibodies and Blue Evans dye.
