Genome-wide Monitoring of CpG Island Methylation With Agilent's Tiling Microarray Technology

Abstract: DNA methylation profiling has emerged as an important technique for understanding the role methylation plays in cellular processes and as a potential diagnostic and prognostic indicator in diseases such as cancer. Of increasing importance is the ability of the researcher to observe genome-wide methylation patterns in multiple samples. We have combined tiling CpG Island Microarrays with the methyl DNA immunoprecipitation method (mDIP;Weber et al., 2005) to compare relative methylation patterns across CpG islands in two model systems — X-chromosome inactivation and cancer profiling. This application note introduces the protocol and highlights data generated.
