Figure Lengend Snippet: Comparison of methylation data between MeDIP/NimbleGen Promoter + CpGi Array and Sequenom MassArray: Stk31 CpGi promoter region . The Stk31 gene region with a CpGi promoter region that is methylated in the liver, but not in ES or testis cells. The box indicates the position of the methylation peak in the liver that overlaps with the CpGi promoter region analyzed by Sequenom. In the epigram of Sequenom methylation analysis shown at the bottom panel, the blue circles indicate 100% methylation, green circles indicate around 50%methylation and yellow circles indicate 0% methylation. The results from biological duplicate samples are shown. The bottom lane (Sequenom Methylation Analysis) shows the results of analysis of testis DNA after in vitro methylation using M. Sss1 methylase (New England Biolabs).
Article Snippet: Sequenom MassArray quantitative methylation analysis of bisulfite treated DNA was performed as an additional means to confirm DNA methylation peaks obtained by MeDIP/NimbleGen Array for both selected and randomly chosen MeDIP methylated regions.
