EZ DNA Methylation Kit
EZ DNA Methylation Kit
- 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.
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.

Q1: Is an incubation with desulphonation buffer for longer than 20 minutes recommended?
Leaving the desulphonation buffer on the column longer than recommended will cause more degradation and subsequently result in lower yields.
Q2: Tips for bisulfite primer design?
Q3: Which polymerase is recommended for amplification from bisulfite converted DNA?
ZymoTaq DNA Polymerase has been specifically designed for use in bisulfite amplification reactions. ZymoTaq is available as a stand-alone polymerase (E2001/E2002), PreMix (E2003/E2004), and qPCR PreMix (E2054/E2055).
Q4: Does bisulfite conversion only occur in a CpG context?
Bisulfite conversion will work regardless of context, so the kits are compatible with genomic DNA derived from plants and other species with high non-CpG methylation levels.
Q5: What is the minimum DNA size that can be recovered?
> 50 bp.
Q6: How to quantify / visualize converted DNA?
Following bisulfite treatment of genomic DNA, nonmethylated cytosine residues are converted into uracil. The recovered DNA is typically A, U, and T-rich. The original base-pairing no longer exists. Instead, it is single stranded with limited non-specific base-pairing at room temperature. The absorption coefficient at 260 nm resembles that of RNA. Use a value of 40 μg/ml for Ab260 = 1.0 when determining the concentration of the recovered bisulfite-treated DNA. To visualize, run converted DNA on agarose gel then chill the gel on ice for 30 minutes. The expected smear will be between 100-1500bp.
Q7: What leads to poor conversion efficiency/ low yields?
Poor conversion efficiency and low yields can be due to a variety of different experiment-specific conditions. Please contact Technical Support to discuss your specific experimental conditions and further troubleshoot with a product specialist.
Q8: How long is bisulfite converted DNA stable at -20 °C?
Converted DNA should be eluted in M-Elution Buffer to keep the converted DNA stable for long term storage. If stored properly for long term (<-20C), the samples should last longer than a month. Minimize freeze/thawing to keep the bisulfite converted DNA stable.
