Minimal methylation was detected by using bisulfite sequencing in 8 of the 12 clones selected for bisulfite sequencing. A) Shown here is the percent cytosine methylation at the CpG dinucleotides in the liver DNA, sperm DNA, and in vivo-produced blastocyst DNA for the regions analyzed by using bisulfite sequencing in clones CC C1, EEE D4, EE A11, K D3, L E8, O D10, QQ E4, and S E3. B) Bisulfite analysis data and the microarray analysis data are in agreement for 37.5% (6/16) of the samples (shown in bold type). The ratios produced from the microarray and bisulfite analysis were classified as consistent when the bisulfite analysis-produced ratio indicated the sample was hypomethylated (>1) or hypermethylated (<1) and matched the methylation status of the microarray-produced data. From the microarray-produced ratios, the samples were classified as hypermethylated when the ratio was < 0.8 and the sample was classified as hypomethylated when the ratio was >1.2. The ratios produced from bisulfite analysis data and the microarray analysis data are not in agreement for 62.5% (10/16) of the samples (shown in parentheses). The microarray values are LOWESS normalized Cy5/Cy3 ratios representing the methylation status of the specified clones in the liver (Cy5) and in vivo-derived blastocyst (Cy3) samples. The Bisulfite ratios (Ref/Sample) were calculated from the equation shown in the Materials and Method section.
