  • Product overview

    DNA methylation is a covalent modification of the cytosine ring at the 5' position of a CpG dinucleotide which leads to epigenetic inactivation of genes when found in 5'-CpG-3'dinucleotides within promoters or in the first exon of genes. It has been demonstrated that DNA methylation plays an important role in the regulation of gene expression, tumorigenesis, and other genetic and epigenetic diseases, and that alterations in DNA methylation patterns are associated with cancer.

    Methylated DNA Immunoprecipitation (MeDIP) Kit - DNA (ab117133) enables the user to enrich methylated DNA by using an antibody specific to methyl cytosine (5-mC) to immunoprecipitate methylated genomic DNA (MeDIP). The enriched methylated fractions can then be used in various downstream applications including qualitative and quantitative PCR, as well as southern blot and DNA microarray.

  • Notes

    NOTE: the size of this kit is based on number of TESTS not SAMPLES. A test simply refers to a single assay well. If you are not sure which size is most suitable for you, contact our Scientific Support Team.



  • MeDIP was performed using 1μg of DNA with ab117133.  Real-time PCR was carried out with MeDIP DNAs and the frequency of DNA methylation of immunoprecipitated DNA vs input DNA was calculated.

  • Captured methylated DNA was used for analyzing methylation level of GAPDH and MLH1 promoter with the use of primers and probes specific to GAPDH and MLH1 promoters, respectively.
  • For enrichment of methylated DNA using ab117133, DNA (0.5 ug) isolated from MCF-7 cells was added into the microwell. Methylated DNA was captured by 5-mC antibody prebound to the microwells.

Both of these kits (ab117133 and ab117135) will immunoprecipitate methylated DNA. The ab117133 Kit uses purified DNA as starting materials while the ab117135 Kit uses cells as starting materials. I can confirm that the immunoprecipitated products are s...

Thank you for your inquiry.

With use of this kit, about 40 ng/well of meDNA can be generated from 500 ng of inputgenomic DNA. Thus, at least 20 ug of genomic DNA (in 40 wells) are needed for generating 1.5 ug of methylated DNA.

Thank you for your inquiry.

You will need 1 well per plate dedicated to the negative control if you're running all at the same time. So for 60 samples you'd probably need to orderone 48 sample kit and one 24 sample kit. The kits are in strip ...

The pre-sonicated DNA sample can be used if the DNA is in the buffer(such as TE containing low concentration of salts) that would not interfereantibody binding to the meDNA, or use MC2 to ...

I am sorry this product did not perform as stated on the datasheet and for the inconvenience this has caused. As requested, I have issued a free of charge replacement for one EpiSeeker methylated DNA Immunoprecipitation (MeDIP) Kit - DNA (ab117133). Read More

I apologize again for the incorrect information given originally.

For tissues we recommend, ab117136.
In comparison, kit ab117135 would be used when starting with cells. When using a DNA sample, please use ab117133 instead.
