A complete and reliable bisulfite conversion kit that eliminates cumbersome DNA precipitation steps and allows DNA bisulfite conversion directly from blood, tissue, and cells without prior DNA purification.

Highlights


  • Complete bisulfite conversion of DNA directly from blood, soft tissue, cells, FFPE samples, and LCM samples.
  • Compatible with small sample inputs as few as 10 cells or 50 pg of DNA.
  • DNA recovered by this bisulfite conversion kit is ideal for downstream analyses including PCR, endonuclease digestion, sequencing, microarrays, etc.

Description


The EZ DNA Methylation-Direct kit is a bisulfite conversion kit that features reliable and complete DNA bisulfite conversion directly from blood, tissue, and cells without the prerequisite for DNA purification. The increased sensitivity of this bisulfite conversion kit makes it possible to amplify bisulfite-converted DNA from as few as 10 cells or 50 pg DNA. Recovered bisulfite-converted DNA is ideal for downstream analyses including PCR amplification, endonuclease digestion, sequencing, microarrays, etc.

Bisulfite treatment of DNA from fibroblast cells of Aicardi-Goutières syndrome (AGS) patients was performed using the EZ DNA Methylation-Direct Kit prior to MethylC-seq. Results showed a global loss of DNA methylation from patients with TREX1, RNASEH2, and SAMHD1 mutations, indicating epigenetic abnormalities in AGS.

In this publication, researchers investigated the regulatory effects of BRCA and glucocorticoid receptor (GR). Genomic DNA extracted from both ovarian cancer and normal ovarian tissue was bisulfite converted using EZ DNA Methylation-Direct Kit and BRCA1 promoter methylation was analyzed. Immunochemistry, real-time PCR, regression analysis, knockdown, and overexpression experiments were also performed to examine the relationship between BRCA1 and GR expression levels, which were found to positively correlate in cancer tissues.

Epigenetic changes were shown to be induced in the midbrain of adult mice by social isolation from 3-6 months of age. Genomic DNA was isolated from the midbrain of the “lonely” mice and was bisulfite converted using the EZ DNA Methylation-Direct Kit. Bisulfite pyrosequencing was performed and the researchers found that social isolation of adult male C57BL/6 mice led to global DNA methylation changes in the midbrain.
