Figure 1From: Nitric oxide induces MUC5AC mucin in respiratory epithelial cells through PKC and ERK dependent pathwaysEffects of the NO donor, NOR-1 on nitric oxide secretion from the A549 cells. The nitrite and nitrate concentrations were measured at 540 nm by Griess reagent method after stimulation with different concentrations of NOR-1 for 3 hours.Back to article page
