Methyl-DNA Immunoprecipitation Validated Immunofluorescence Validated Dot Blot Validated

Application Notes

Applications Validated by Active Motif:
MeDIP: 1 - 2 µg per IP
MeDIP-Seq: 1 - 2 µg each
DB: 0.5 - 2 µg/ml dilution

In MeDIP, the DNA must be denatured when using this antibody. For 5-methylcytosine, we also offer AbFlex® 5-methylcytosine Recombinant Antibody (rAb). For details, see Catalog No. 91187.

This 5-Methylcytosine (5-mC) antibody was raised against 5-Methyl-cytidine conjugated to KLH and recognizes 5-Methylcytosine.


Purified IgG in PBS with 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.


Next-Gen sequencing data generated using 5-Methylcytosine (5-mC) antibody (mAb) correlates well with CpG density.
DNA was enriched from 1 ug of denatured, adaptor ligated human PC9 cell DNA using 2 ul of the 5-Methylcytosine (5-mC) antibody (mAb). MeDIP DNA was sequenced using the Illumina platform to generate 26 million sequence tags. Tags were mapped to generate a whole-genome DNA methylation profile. The image above shows that the enriched regions (purple peaks) correlate well with CpG density (green overlay).

5-Methylcytosine (5-mC) antibody (mAb) tested by Methyl-DNA Immunoprecipitation (MeDIP).
Human DNA (500 ng) digested with MseI was subjected to MeDIP using 2 µg of the 5-Methylcytosine antibody and then analyzed by quantitative real-time PCR with primers specific for ZC3H13 that is normally methylated or Untr1 that is normally unmethylated. The MeDIP'd DNA (enriched DNA) was plotted.

5-Methylcytosine (5-mC) antibody (mAb) tested by dot blot analysis.
DNA from the Methylated DNA Standard Kit (Catalog No. 55008) were spotted (5 ng per spot) on to a positively charged nylon membrane and blotted with 5-Methylcytosine antibody (2 µg/ml dilution).

Lane 1: single-stranded unmethylated DNA.
Lane 2: single-stranded DNA containing 5-methylcytosine.
Lane 3: single-stranded DNA containing 5-hydroxymethylcytosine.
Lane 4: double-stranded unmethylated DNA.
Lane 5: double-stranded DNA containing 5-methylcytosine.
Lane 6: double-stranded DNA 5-hydroxymethylcytosine.


5-Methylcytosine (5-mC) is a modified base that is found in the DNA of plants and vertebrates. DNA methylation is an epigenetic event in which DNA methyltransferases (DNMTs) catalyze the reaction of a methyl group to the fifth carbon of cytosine in a CpG dinucleotide. This modification helps to control gene expression and is also involved in genomic imprinting, while aberrant DNA methylation is often associated with disease. The 5-methylcytidine antibody (Clone A1) has been developed to discriminate between the modified base and its normal cytosine counterpart, allowing for gene promoter methylation analysis.
