Human DNA (500 ng) digested with Mse I was subjected to MeDIP and then analyzed by quantitative real-time PCR with primers specific for genes that are normally methylated (Xist, NYESO and SNRPN) or unmethylated (APC and p48). The MeDIP'd DNA (enriched DNA) was plotted.

Background

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-methylcytidine antibody (Clone 33D3) 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.
