Anti-Dnmt1 Antibody, clone DNM-2C1

DNA (cytosine-5)-methyltransferase 1 (Dnmt1) is one of three mammalian enzymes that catalyze the addition of a methyl group to the 5’ carbon of cytosine residues in CpG dinucleotides. These methylation marks are heritable modifications that are transferred to new DNA molecules following replication, by the activity of Dnmt1, and possibly Dnmt3a and Dnmt3b. Dnmt1 recognizes hemimethylated CpG regions with the aid of the UHRF1 protein, and it mediates the methylation of cytosines at those sites. DNA methylation has been linked to chromosome stability and gene expression in somatic cells; and to parental imprinting and X-chromosome inactivation in germ cells. Several studies have indicated that DNA methylation patterns are altered in various cancers.

His-tagged recombinant protein corresponding to human Dnmt1.

Anti-Dnmt1 Antibody, clone DNM-2C1 is a Rat Monoclonal Antibody for detection of Dnmt1 also known as DNA (cytosine-5)-methyltransferase 1 & has been validated in IP, ChIP & WB.

Immunoprecipitation Analysis: A representative lot was used by an independent laboratory to detect Dnmt1 in IP (Felle, M., et al. (2011). Nucleic Acids Res. 39(19):8355-8365.).

Chromatin Immunoprecipitation Analysis: A representative lot was used by an independent laboratory to immunoprecipitate Dnmt1 in ChIP (Felle, M., et al. (2011). Nucleic Acids Res. 39(19):8355-8365.).
