Abstract

See full text

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.
