Effects of agonistic and antagonistic anti-Fas Abs on Jurkat cells.
Jurkat cells (20 000) were cultured in 100 μL RPMI 1640 with 10% FCS in the absence or presence of 1 μg/mL CH11 (agonistic anti-Fas Ab) and/or ZB4 (blocking anti-Fas Ab) at different concentrations as indicated. Following 24 hours incubation, each well was pulsed for 24 hours with 1 μCi [3H]TdR before being harvested and evaluated for [3H]TdR uptake (cpm) as described in “Materials and methods.” Each group was performed in triplicate and error bars represent SD.
