Figure 2From: The application of methylation specific electrophoresis (MSE) to DNA methylation analysis of the 5' CpG island of mucin in cancer cells (A) Analysis of the methylation status of A427 (A) and LS174T (L) by MSE and conventional bisulfite-DGGE. (B) Determination of the resolution of MSE detection. A mixture of a high methylation cell line (Panc1) and a low methylation cell line (BxPC3) was analyzed. The number shows the BxPC3 contamination ratio. The upper band (arrow) shows the digitalized emission intensity using Image J. On the graph, the Y-axis shows the intensity of the upper band and the X-axis shows the BxPC3 contamination ratio. Regression equation: Y = 243 . 26X + 187 . 25 ; correlation co-efficient: R2 = 0.993. Data were averaged from 3 separate experiments.Back to article page
