EZ DNA Methylation-Gold Kit


  • Complete bisulfite conversion of DNA in less than 3 hours.
  • Desulphonation and recovery of bisulfite-treated DNA with a spin column.
  • Recovered DNA is ideal for downstream analyses such as PCR, endonuclease digestion, sequencing, microarrays, etc.


The EZ DNA Methylation-Gold Kit is a refinement of our popular EZ DNA Methylation kit and uses heat denaturation instead of chemical denaturation of the input DNA. This allows for the denaturation and bisulfite conversion steps to be consolidated into one step, leading to a much-reduced incubation time. Recovered bisulfite-converted DNA is ideal for PCR amplification for downstream analyses including endonuclease digestion, sequencing, microarrays, etc.

Researchers from the National Institute of Plant Genome Research in New Delhi used the EZ DNA Methylation-Gold Kit to identify the level of cytosine methylation in genomic DNA from Tomato leaf curl New Delhi virus. Through DNA methylation-specific RNA silencing, the researchers aimed to target the viral genomic regions of this virus to potentially determine an alternate defense mechanism for generating transgenic plants to prevent yield loss.

The EZ DNA Methylation-Gold Kit was used to bisulfite convert DNA extracted from Thy-1 (+) and Thy-1 (-) lung fibroblasts and tissue. Data from methylation-specific PCR and bisulfite sequencing enabled researchers to show that epigenetic regulation of Thy-1 could be a novel and potentially reversible mechanism in fibrosis that may offer the possibility of new therapeutic options.

Researchers from China analyzed the role of DNA methylation in the life cycle of a parasitic nematode, Trichinella spiralis and characterized the methylome of three life-cycles states in this organism. Genomic DNA of T. spiralis muscle larvae, adults, and new-born larvae was isolated and methylated cytosine levels were determined by MethylC-seq.

“It makes gene specific DNA methylation analysis very simple and anyone with modest technical background can easily perform the experiment using this kit.”

“This protocol allows for bisulfite conversion in about 3 hours. This fast conversion is particularly relevant to our experiments, which allows us to PCR amplify and clone the products in 1 day, saving time without loss of quality.”
