<p>The invention refers to a nucleic acid for providing a standard in the quantitative bisulfite based analysis of the methylation status of a DNA molecule with a given sequence, wherein the given sequence comprises at least one CpG position that is to be analyzed for its methylation status. This nucleic acid comprises: a first and a second sequence portion, both of which comprise at least part of the given sequence with at least one CpG position, wherein in the first sequence portion, all of the CpG positions represent the methylated status, and in the second sequence portion, all of the CpG positions represent the unmethylated status.</p> |
