Figure 3From: Reproducibility and intraindividual variation over days in buccal cell DNA methylation of two asthma genes, interferon γ (IFNγ) and inducible nitric oxide synthase (iNOS)Concordance correlations between duplicate samples for (a) CpG-186 (left, n = 11) and CpG-54 (right, n = 13) on interferon (IFNγ) proximal promoter; (b) CpG-359 (left, n = 11) and CpG-352 (right, n = 10) located in the inducible nitric oxide synthase (iNOS) proximal promoter proximal promoter. Samples were collected from sequential buccal swabs minutes apart.Back to article page
