Figure 4From: Determination of quantitative and site-specific DNA methylation of perforinby pyrosequencingThe pattern of methylation in 32 CpG sites in 1.4 kb PRF1 promoter using DNA from whole blood and PBMCs from normal subjects. Y-axis, methylation level (%) ± SD. X-axis, CpG sites 1–32. Methylation levels at each CpG site represent mean of 5 normal subjects.Back to article page
