DNA methylation is an epigenetic mechanism of regulation, which is responsible for transcriptional silencing of tumor suppressor genes. Without any change of DNA sequence, phenotype can be differentiated by epigenetic changes, and the changes are heritable through cell cycles and generations. Therefore, heterogeneity of DNA pattern in a specific tissue provides significant biological information. However, there is no technology which can detect those heterogeneous patterns quantitatively although DNA methylation detection method in omogeneous sample is available. High-resolution capillary electrophoresis-based single strand conformation polymorphism analysis (CE-SSCP) system has great potentials in quantitative DNA methylation analysis since sequence change can be easily detected by mobility change. In this study, we developed a quantitative DNA methylation analysis method based on high-resolution CE-SSCP system combined with sodium bisulfite conversion using E-cad and p14 gene as a model. In a single reaction, a mixture of various methylation patterns could be easily analyzed and this result indicates that this technique has a huge potential as an epigenetic diagnosis system.
