摘要:
The invention relates to a method for quantitatively determining the methylation rate of a nucleic acid through sequencing. According to the invention, the method comprises at least the following steps: a) treating the nucleic acid with a chemical reagent or an enzyme containing solution, whereby the base pairing behavior of methylated cytosine bases and/or unmethylated cytosine bases of the nucleic acid are altered such that methylated cytosine bases become distinguishable from unmethylated cytosine bases, and b) introducing into the nucleic acid at least one base for generating a sequencing signal to be used as a reference signal for normalization, and c) sequencing the nucleic acid, whereby a signal from each cytosine base of the nucleic acid, or a signal from each guanine base of the nucleic acid and a reference signal from the at least on introduced base is obtained, and d) normalizing the signal obtained from each cytosine base of the nucleic acid, or the signal obtained from each guanine base of the nucleic acid to the reference signal from the at least one introduced base.
摘要:
The invention relates to a method for sensitively and specifically detecting cytosine methylations. For this purpose, DNA is first analysed by reacting with the aid of a methylation specific restriction enzyme. In such a way, the background DNA is removed from a reaction preparation. At a next step, a specific conversion of a non-methylated cytosine is carried out, while a methylated cytosine remains unchanged. The converted DNA can be analysed according to different methods, in particular by means of real time PCR method.

摘要:
Aspects of the present invention relate to the determination of the DNA methylation level at one or more CpG position within cells of a defined type in a tissue sample. This methylation level is deduced from the total DNA methylation level of all cells of the sample and from the content of said cells of interest. In aspects of the invention, the cell content is determined by means of histopatholoy, staining methods, antibodies, expression analysis or DNA methylation analysis.
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:
The present invention relates to methods and kits for preserving genomic DNA sequence complexity within chemically and/or enzymatically converted DNA by an enzyme or series of enzymes that adds a methyl group to a cytosine outside of CpG dinucleotide sequences of genomic DNA. Further, the present invention relates to methylation analysis of the genomic DNA.
