Abstract: A method is described for the detection of the degree of methylation of a specific cytosine in the sequence context 5?-CpG-3? of a genomic DNA sample. In the first step, the genomic DNA is chemically treated in such a way that the cytosine bases are converted to uracil, but not the 5-methylcytosine bases.

Abstract: A method is described for the detection of 5-methylcytosine in genomic DNA samples. First, a genomic DNA from a DNA sample is chemically converted with a reagent, whereby 5-methylcytosine and cytosine react differently. Then the pretreated DNA is amplified with the use of a polymerase with primers of different sequence. In the next step, the amplified genomic DNA is hybridized to an oligonucleotide array and PCR products are obtained, which must be provided with a label. Alternatively, the PCR products can be extended in a primer extension reaction, wherein the extension products are also provided with a label. In the last step, the extended oligonucleotides are investigated for the presence of the label.

Abstract: A method for the detection of cytosine methylation in DNA samples is described. First, DNA is extracted from a sample and bound to a surface. In the second step, a genomic DNA sample is preferably treated with a bisulfite (=disulfite, hydrogen sulfite), such that all unmethylated cytosine bases are converted to uracil, while the 5-methylcytosine bases remain unchanged. In the third step of the method, one or more oligonucleotides is (are) hybridized to the treated DNA as primers. In the fourth step of the method, the hybridized primer(s) is or are elongated in a polymerase reaction. Here, labeled guanine nucleotides are preferably utilized which are essentially incorporated only if cytosine bases were still present in the treated DNA. Consequently, the extent of incorporation of guanine bases and thus also the number of incorporated labels is proportional to the methylation in the DNA sample under investigation.
