| 摘要 |
The invention provides a method for obtaining DNA after bisulfite reaction which can be stored with libraries in genome reserved and has excellent storage stability, and a method for detecting methylated cytosine. Specifically, the invention provides a method for obtaining DNA complementary to single-stranded DNA in which non-methylated cytosine has been uracilated by subjecting single-stranded DNA to a bisulfite reaction and then a reverse transcriptase reaction. The resulting complementary DNA can be amplified by a PCR reaction. Methylated cytosine can be detected in single-stranded DNA by subjecting the single-stranded DNA, in order, to a bisulfite reaction, a reverse transcriptase reaction, and a PCR reaction, and then subjecting the obtained PCR amplification product to nucleotide sequence analysis. |
