    • The present invention provides a method for identifying a methylated CpG containing nucleic acid by contacting a nucleic acid with a methylation sensitive restriction endonuclease that cleaves unmethylated CpG sites and contacting the sample with an isoschizomer of the methylation sensitive restriction endonuclease, which cleaves both methylated and unmethylated CpG sites. The method also includes amplification of the CpG-containing nucleic acid using CpG-specific oligonucleotide primers A method is also provided for detecting an age associated disorder by identification of a methylated CpG containing nucleic acid. A method is further provided for evaluation the response of a cell to an agent A kit useful for detection of a CpG containing nucleic acid is also provided. Nucleic acid sequences encoding novel methylated clones.
    • 本发明提供了通过使核酸与切割未甲基化CpG位点的甲基化敏感性限制性内切核酸酶接触并使样品与甲基化敏感性限制性内切核酸酶的异构体接触的方法来鉴定含甲基化CpG的核酸,其将甲基化和未甲基化 CpG位点。 该方法还包括使用CpG特异性寡核苷酸引物扩增含CpG的核酸。还提供了通过鉴定含甲基化CpG的核酸来检测年龄相关疾病的方法。 还提供了用于评估细胞对试剂的反应的方法。还提供了可用于检测含CpG的核酸的试剂盒。 编码新甲基化克隆的核酸序列。
