Figure 3From: The use of DNA from archival dried blood spots with the Infinium HumanMethylation450 arrayUnsupervised clustering plot based on the methylation (M) values of the number of variable genes. Samples from the same individual (GC, dried blood spot; BC, buffy coat) are labelled with the same number. Duplicates from individual 1 are labelled with _T2. The clustering analysis was performed on the top 101,691 most variable probes (CV > 0.2). The variable probes were selected by calculating the Coefficient of Variance (CV, standard deviation/mean).Back to article page
