for 5-Methylcytosine (5-mC) antibody (mAb) (Clone 33D3)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.

Clone 33D3 recognizes the modified base 5-methylcytidine found in plant and vertebrate DNA.
for 5-Methylcytosine (5-mC) antibody (mAb) (Clone 33D3)Application Notes
This 5-Methylcytosine antibody has been validated for use in applications including flow cytometry (1:500), dot blot (1:1,000) immunohistochemistry (1:500) and methylated DNA immunoprecipitation (MeDIP, 1 µg per IP).
for 5-Methylcytosine (5-mC) antibody (mAb) (Clone 33D3)Buffer
Purified IgG in 10 mM phosphate, 0.15 M NaCl and 0.01% thimerosal. Thimerosal is highly toxic.
Bridging Antibody to Improve ChIP, MeDIP and IP
Some isotypes of mouse IgG antibodies do not bind well to protein G-conjugated agarose/magnetic beads, which are commonly used in ChIP, MeDIP and IP experiments. Capture efficiency can be improved by including an anti-mouse IgG bridging antibody because it binds with a strong affinity to both the protein G beads and the mouse IgG antibody. By increasing the affinity of the mouse primary antibody for the protein G bead, the Bridging Antibody for Mouse IgG can help improve the results of all ChIP, MeDIP and IP experiments that use 5-Methylcytosine (5-mC) antibody (mAb).

5-Methylcytosine antibody (mAb) (Clone 33D3) tested by Methyl-DNA Immunoprecipitation (MeDIP).
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.
