    摘要: The present invention provides, inter alia, a method for generating a genome-wide epigenomic map, comprising a correlation between methylation variable CpG positions (MVP) and genomic DNA sample types. MVP are those CpG positions that show a variable quantitative level of methylation between sample types. Particular genomic regions of interest (ROI) provide preferred marker sequences that comprise multiple, and preferably proximate MVP, and that have novel utility for distinguishing sample types. The epigenic maps have broad utility, for example, in identifying sample types, or for distinguishing between and among sample types. In a preferred embodiment the epigenomic map is based on methylation variable regions (MVP) within the major histocompatibility complex (MHC), and has utility, for example, in identifying the cell or tissue source of a genomic DNA sample, or for distinguishing one or more particular cell or tissue types among other cell or tissue types. Analysis of epigenetic characteristics of one, or of a set of nucleic acid sequences, in the context of an inventive epigenomic map, allows for the determination of an origin of the nucleic acids.

    摘要: Described is a method for detecting 5-methylcytosine in genomic DNA samples. First, a genomic DNA from a DNA sample is chemically converted with a reagent, 5-methylcytosine and cytosine reacting differently, and the pretreated DNA is subsequently amplified using a polymerase and at least one primer. In the next step, the amplified genomic DNA is hybridized to at least one oligonucleotide, forming a duplex, and said oligonucleotide is elongated by at least one nucleotide, the nucleotide carrying a detectable label, and the elongation depending on the methylation status of the specific cytosine in the genomic DNA sample. In the next step, the elongated oligonucleotides are analyzed for the presence of the label.

    摘要: A method is described for the amplification of nucleic acids, in which the segments to be amplified are first hybridized with at least two primer oligonucleotides that have two domains, wherein the sequence-specific domain found at the 3-end hybridizes to the segment to be amplified, while the generic domain found at the 5-end does not hybridize. Then an amplification reaction is conducted by means of a polymerase and subsequently a labeled primer oligonucleotide, which binds to the generic domain of the first primer, is hybridized to the amplificate which is formed. In the last step, the sequence of the amplificate is investigated.

    摘要: The present invention concerns a method for the detection of cytosine methylation in DNA samples, wherein the following steps are conducted: (a) a genomic DNA sample, which comprises the DNA to be investigated and background DNA, is chemically treated in such a way that all of the unmethylated cytosine bases are converted to uracil, whereas the 5-methylcytosine bases remain unchanged; (b) the chemically treated DNA sample is amplified with the use of at least 1 primer oligonucleotide as well as a polymerase, whereby the DNA to be investigated is preferred as the template over the background DNA, and (c) the amplified products are analyzed and the methylation status in the DNA to be investigated is concluded from the presence of an amplified product and/or from the analysis of additional positions.
