Figure 2From: Promoter methylation analysis of O6-methylguanine-DNA methyltransferase in glioblastoma: detection by locked nucleic acid based quantitative PCR using an imprinted gene (SNURF) as a reference Direct Sequencing of SNURF promoter. Direct sequencing after bisulfite modification of two CpGs of SNURF for case BF215. The arrows indicates the simultaneous presence of C/T (C: black peak; T: blue peak) due to a balanced amount of methylated and unmethylated cytosine in the CpGs amplified with our primer set.Back to article page
