High-level superoxide production in transgenic COS-phox cells.
Superoxide production by either wild-type COS-7 cells (▪) or transgenic COS-phox cells (■), following detachment from tissue-culture dishes and stimulation with either 0.4 μg/mL PMA or 100 μM AA, was determined by reduction of ferricytochromec. Data are expressed as mean ± SD; n ≥ 3.
