The effect of alternative culture conditions on the phosphorylation of NF-κB p65. Macrophages from smoking controls (A; n = 4) and COPD patients (B; n = 4) were cultured for 15 min (1a), 30 min (1b), 60 min (1c), or 16 h (2). Data shown are mean ± SEM of phosphorylated NF-κB p65 protein band density normalised to β-actin. Representative Western blot protein bands are shown below respective conditions on the chart.
