HIV-1 persistently-infected lymphoid J1.1 and monocytic U1 cells were treated with TNF-α and PMA respectively in order to stimulate viral replication. P24 antigen was determined at 0, 24 and 48 h in cell supernatants by ELISA (HIVAG-1 Monoclonal, Abbot Laboratories). Values correspond to p24 antigen per 200,000 cells, expressed in J1.1 as pg/ml and in U1 Cells as ng/ml.
