Fig. 2From: Batch-effect detection, correction and characterisation in Illumina HumanMethylation450 and MethylationEPIC BeadChip array dataSelected Infinium control probes. Across the EpiSCOPE study data, outlier slides were observed for the staining (a), target removal (b), and c extension control probes. For the BFiN study data, the Type I (d) and Type II (e) bisulphite conversion control probes showed evidence of reduced bisulphite conversion efficiency for slides 13–22Back to article page
