The MethylCode™ Bisulfite Conversion Kit is a fast and easy way to convert unmethylated cytosines from a DNA sample into uracils while methylated cytosines remain unchanged.

The modified DNA is ideal for PCR amplification for downstream analyses, including restriction endonuclease digestion, sequencing, and microarrays. With the MethylCode™ Bisulfite Conversion Kit you can expect:

–Simple, rapid cytosine methylation detection

–Consistency across most experimental conditions
–Streamlined conversion of unmethylated cytosines into uracil, thanks to a coupled DNA denaturation/bisulfite treatment step
–Ultra-pure DNA ideal for subsequent molecular-based analyses



Kit specifications:

–Protocol: Rapid heat denaturation of DNA followed by sodium bisulfite modification with spin column purification

–Sample sources: Plasmid, genomic, and endonuclease digested DNAs
–Input DNA: 500 pg-2 μg DNA per treatment, with 200-500 ng being optimal
–Recovery volume: Purified, bisulfite-treated DNA is recovered in 10 μl elution buffer

Preguntas frecuentes

I think my DNA may be under-converted (incomplete). What can you suggest?

Ensure that the DNA that you use with the MethylCode Bisulfite Conversion Kit is ultra clean. If particulate matter is present after adding the CT Conversion Reagent, then centrifuge the material at high speed and perform the conversion with the clear supernatant. Also, ensure that all of the liquid is at the bottom and not in the cap or walls of the PCR tube, prior to performing the conversion reaction

How can I quantify my DNA after bisulfite conversion?

Checking your converted sample by O.D.260/280 tends to be inconsistent. We suggest performing qPCR or agarose gel electrophoresis and comparing your sample to a known amount of DNA to quantify your DNA after bisulfite conversion.

How should I store my converted DNA after it is eluted from the column?

The converted DNA is stable for one day at room temperature, one week at 4 degrees C, and two to four months at -20 degrees C. We recommend on storing your converted DNA below -70 degrees C whenever possible (remember: the DNA is single-stranded and inherently less stable than dsDNA).

How long can I store the CT Conversion Reagent in the MethylCode Bisulfite Conversion Kit after it has been dissolved?

The CT Conversion Reagent that has been prepared in solution may be stored up to 1 week at -20 degrees C. We recommend thawing at room temperature and mixing for 2 mins by rotating or vortexing before use.

My PCR post-bisulfite conversion failed. What can you suggest?

Here are some recommendations:

- Primers: Ensure that your primers are designed to amplify the converted template. We recommend primers that are 24-32 nts in length and contain no more than 2-3 mixed bases (for base-pairing to C or T residues). The 3' end of your primer should not contain a mixed base or end in a residue whose conversion state is unknown.
- Polymerase: We recommend using a hot-start Taq polymerase such as Platinum Taq DNA Polymerase, Platinum Taq High Fidelity, or AccuPrime Taq DNA Polymerase. Proof-reading polymerases are not recommended because they cannot read through uracil present in DNA templates.
- Amplicon size: Bisulfite modification is harsh and may cause strand breaks. Most research publications recommend 200 bp lengths. Larger amplicons can be generated, but this requires an optimized protocol.
- Template DNA: We recommend using 2-4 µl of eluted DNA for each PCR reaction. Ensure that total template DNA is less than 500 ng.
