Published: March 2021

The oxidation activity of the mammalian ten-eleven translocation dioxygenase (TET) on 5-methylcytosine (5mC) of DNA is usually monitored by analytical methods such as dot blotting and liquid chromatography-mass spectrometry (LC-MS). Herein, we describe a high throughput capillary gel electrophoresis assay for monitoring the in vitro oxidation of 5mC by TET. The method is rapid and quantitative, and can serve as a powerful tool in mechanistic studies of TET.
