  • Purified cells were stimulated as indicated and supernatants were collected after 24 (for IL-2) or 72 h. The amount of cytokine was determined by ELISA. Data represent the average values (pg/ml) of pooled data from four independent experiments. Cytokine production by allogeneic APCs alone has been subtracted.
