The three mammalian 5-methylcytosine (5-mC) dioxygenases (Ten Eleven Translocation (TET); TET1, TET2, and TET3 in humans) convert 5-mC to 5-hydroxymethylcytosine (5-hmC) and subsequently to 5-formylcytosine (5-fC) and 5-carboxylcytosine (5-caC). This series of modifications is thought to represent one pathway to active DNA demethylation, thereby reshaping the methylated DNA landscape established by DNA methyltransferases (DNMTs). In addition, these marks, particularly 5-hmC, have been shown to be distinct epigenetic signatures in their own right impacting stem cell and cancer cell biology.

GeneTex introduces a selection of antibodies to targets relevant to DNA methylation and demethylation. We are proud to note that many of these antibodies are suitable for ChIP/ (h)MeDIP application.
