EZ DNA Methylation-Startup Kit
EZ DNA Methylation-Startup Kit
- The complete solution for bisulfite conversion. This all-in-one kit contains reagents for bisulfite conversion of DNA without the need for purification, methylated human DNA with control primers, and a robust hot-start PCR polymerase that is specifically formulated for bisulfite-converted DNA.
- Designed for the first-time user requiring a consolidated product to control for bisulfite conversion.
- Kit includes: one EZ DNA Methylation-Direct kit, one fully methylated Universal Methylated Human DNA Standard, and ZymoTaq DNA Polymerase.
The EZ DNA Methylation-Startup Kit provides the necessary tools for complete bisulfite conversion of DNA for methylation analysis. This kit includes reagents that allow for bisulfite conversion of purified DNA and DNA directly from blood, cells, and fresh or FFPE tissues without the prerequisite for upstream DNA purification. A fully methylated Universal Methylated Human DNA Standard is provided with a special primer set for PCR to assess conversion efficiency. Finally, a unique ZymoTaq DNA Polymerase is included for robust amplification of bisulfite-treated DNA.
|Applicable For||Recovered DNA is ideal for downstream analyses including PCR, endonuclease digestion, sequencing, microarrays, etc.|

|Sample Source||Blood, tissue, cells, FFPE, LCM-derived samples, purified genomic DNA, endonuclease-digested DNA, linearized plasmid DNA, etc.|
Q1: 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.
Q2: How to quantify converted DNA?
For best results, keep the method of quantification consistent before and after bisulfite treatment:
- If quantifying with a NanoDrop, use dsDNA settings (50 μg/ml for Ab260 = 1.0) before treatment and use RNA settings (40 μg/ml for Ab260 = 1.0) after treatment.
- If quantifying with Qubit, use a dsDNA assay before treatment and use a ssDNA assay after treatment.
Q3: How to visualize converted DNA?
Following bisulfite treatment, DNA will be single stranded with limited non-specific base pairing at room temperature. To visualize, run the converted DNA on an agarose gel then chill the gel on ice or in an ice bath for 30 minutes. This will force enough base-pairing to allow intercalation of the ethidium bromide for the DNA to be visible. If using a Bioanalyzer or TapeStation instrument, use RNA kits and reagents to visualize the converted DNA.
Q4: What is the minimum DNA size that can be recovered?
> 50 bp.
Q5: How long is bisulfite converted DNA stable at -20°C?
Converted DNA eluted in M-Elution Buffer can generally be stored at -20°C for 1-3 months. If longer term storage is necessary, we recommend storing at or below -70°C if possible. Bisulfite converted DNA is less stable than dsDNA; for best results, minimize freeze-thawing of converted DNA and use as soon as possible for downstream analysis.
Q6: 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.
Q7: 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.
Q8: 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).
