Published Applications

The following applications have been published using this antibody. Unless noted above, Active Motif may not have validated the antibody for use in these applications:



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.


5-Methylcytosine antibody (pAb) tested by Methyl-DNA Immunoprecipitation (MeDIP).
Human DNA (500 ng) digested with MseI and denatured was subjected to MeDIP and then analyzed by quantitative real-time PCR with primers specific for genes that are methylated (KIAA0853, GEMIN4) or unmethylated (Untr12). The amount of MeDIP'd DNA (enriched DNA) was plotted.

5-methylcytidine antibody (pAb) tested by dot blot analysis.
DNA from the Methylated DNA Standard Kit (Catalog No. 55008) were spotted on to a positively charged nylon membrane and blotted with 5-methylcytidine antibody recognizing 5-methylcytosine (2 µg/ml dilution).

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


5-Methylcytosine (5-Methylcytidine) 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-methylcytosine antibody has been developed to discriminate between the modified base and its normal cytosine counterpart, allowing for gene promoter methylation analysis.

qPCR Primers

Active Motif's Human Positive Control Primer Set ZC3H13 (Cat. No. 71009) and Human Negative Control Primer Set 1 (Cat. No. 71001) have been validated for performing qPCR and endpoint PCR when this antibody has been used for ChIP on human samples. For ChIP experiments with this antibody on mouse samples, the Mouse Negative Control Primer Set 1 (Cat. No. 71011) has been validated for both qPCR and endpoint PCR.

Chromatin IP Assays

This antibody has been validated for use in ChIP and/or ChIP-Seq, and can be used with Active Motif's ChIP-IT® High Sensitivity Kit or our magnetic bead-based ChIP-IT® Express Kits.
