Synthesized oligos containing different numbers of 5-methylcytosines were captured with the Clone 33D3 anti-5-methylcytosine antibody (Cat No. A-1014) and then colorimetrically detected. The results show that the oligos containing as few as two 5-mCs can still be captured and oligos with four or more 5-mCs can be fully captured by the antibody.
Synthesized oligos containing different numbers of 5-methylcytosines were captured with anti-5-methylcytosine antibodies from various companies and then colorimetrically detected for comparison. Results show Epigentek's 5-mC antibody has the highest sensitivity and specificity in capturing methylated DNA fragments.

Product Overview

5-methylcytosine (5-mC) is formed when DNA methyltransferase (DNMT) catalyzes the addition of a methyl group onto the 5-carbon of the cytosine ring, an epigenetic process known as DNA methylation. 5-mC is considered the "fifth" DNA base and this 5-methylcytosine mouse monoclonal antibody is ideal for discriminating between the unmodified cytosine base (C) and the methylated cytosine base (5-mC) for DNA methylation studies. DNA methylation, the major epigenetic modification of eukaryotic genomes, plays an essential role in mammalian development. DNA methylation of promoter regions leads to inactivation of gene function. Also, DNA methylation status varies according to tissue type, and region-specific DNA hypermethylation and global DNA hypomethylation have been demonstrated to play an important role in tumorigenesis.

Application Description
Pros: Only small amount of antibody needed per sample.

Cons: Must denature DNA before using- not mentioned in user manual that it binds single stranded DNA.

Procedural Details
In vitro methylation assay: In vitro methylation assays were performed with 10 ng of a 189-bp gDNA template from the rat Fos promoter (containing 15 CpG sites). A control 5mC strand was created by mixing in methylated dNTPs into PCR reaction. DNA was incubated for 1 h at 37 °C with 0.06mM DNMT3a-3l (Sigma, SRP0396) and 0.5mM S-(50Adenosyl)-L- methyonine (SAM, Sigma) in methylation buffer alongside DNA, protein and SAM only controls. MeDIP was carried out with 10 ul magnetic beads (Protein-A coated Dynabeads Beads, Invitrogen) and 1 ul 5 mC antibody (Epigentek, #A-1014) for 1 h at 4 °C with rotation on ssDNA. Beads were washed 3x with 1 bind/wash buffer for 5 min/wash and re-suspended in buffer EB with 1% SDS. Proteinase K (Qiagen) was added and reactions were incubated at 50 °C for 1 h then 95 °C for 10 min to reverse binding. Beads were removed and IP reactions and inputs were purified using a PCR Purification Kit (Qiagen). Purified DNA was subjected to qPCR, and methylation levels were computed as a fraction of input DNA.

Other Thoughts
Please include in user guide that DNA must be single stranded to bind for applications such as MeDIP.

Co-incubation of DNMT3a/3l protein and the methyl donor SAM results in cytosine methylation at dsDNA from the rat Fos promoter.
Rating by n*****@vanderbilt.edu Verified Customer Date Added: Thursday 22 December, 2016
Application Description
The product is used for detecting DNA methylation level. The DNA was denatured and cross-linked to the membrane. Then incubate with methylcytosine antibody for 1h at RT. After incubation with secondary antibody, developed signal with ECL.

Pros: the steps are simple & the antibody is sensitive.
Cons: not for this one.

Procedural Details
Here is the picture shows that the antibody has a superior sensitivity to 5-methylcytosine over 5-hydroxymethlcytosine. NO detection to cytosine. Also, the antibody can even detect 1ng/ul 5-methylcytosine.

Other Thoughts
the antibody works pretty good to detect DNA methylation
