EZ DNA Methylation kit

Highlights


  • Streamlined, proven procedure for bisulfite conversion of DNA.
  • Desulphonation and recovery of bisulfite-treated DNA with a spin column.
  • Recovered DNA is ideal for downstream analyses including PCR, endonuclease digestion, sequencing, microarrays, etc.

Description


The EZ DNA Methylation Kit features a simplified procedure that streamlines bisulfite treatment of DNA. This kit is the original bisulfite conversion kit from Zymo Research. The EZ DNA Methylation Kit is based on the three-step reaction that takes place between cytosine and sodium bisulfite during which cytosine is converted into uracil. Innovative desulphonation technologies eliminate otherwise cumbersome precipitations. The kit is designed to reduce template degradation and minimize DNA loss during treatment and clean-up, while ensuring complete conversion of the DNA. Purified, converted DNA is ideal for downstream analyses including library preparation for Next-generation sequencing, PCR amplification, endonuclease digestion, sequencing, microarrays, etc. The EZ DNA Methylation Kit is recommended for use with Illumina Infinium MethylationEPIC BeadChip array.

Researchers from Germany used the EZ DNA Methylation Kit to bisulfite convert genomic DNA from ex vivo isolated T cell subsets to study the changes in DNA methylation during differentiation of naïve T cells into Th cell subsets. Further methylome analysis through methylation sensitive high-resolution melting (MS-HRM) and pyrosequencing demonstrated that CD4+ T cells share more demethylated regions with Th17 cells when compared to Th1 cells, and that overall Th17 cells display the highest number of demethylated regions. Through this analysis, the researchers were able to identify a unique Th17-specific epigenetic signature and reinforce the finding that Th cell differentiation is associated with major epigenetic changes.

In a genome-wide study investigating DNA methylation levels in acute myeloid leukemia cells, researchers used the EZ DNA MethylationTM Kit to bisulfite convert genomic DNA obtained from clinical samples. PCR amplification followed by bisulfite sequencing of the converted DNA helped to show that patients diagnosed with acute myeloid leukemia have distinct methylomes in their cancer cells compared to normal cells.

In a study to determine how global DNA methylation patterns change with age, researchers used the EZ DNA Methylation Kit to bisulfite convert genomic DNA blood samples taken from newborn babies and 100+ year old patients. The authors subsequently subjected the bisulfite-converted DNA to whole genome bisulfite sequencing, 450 K CpG site microarray analysis, and bisulfite genomic sequencing and pyrosequencing, and they found that genome wide DNA methylation content significantly decreased with age.
