The TET1 Chemiluminescent Assay Kit is designed to measure TET1 activity for screening and profiling applications. TET1 belongs to the Ten Eleven Translocation (TET) family proteins that catalyze 5-methylcytosine oxidation and generate 5-methylcytosine derivatives, including 5-hydroxymethylcytosine. TET1 may repress gene transcription in a catalytic activity-independent manner.

The key to the TET1 Chemiluminescent Assay Kit is a highly specific antibody that recognizes hydroxymethylated substrate. With this kit, only three simple steps on a microtiter plate are required for detection of TET1 activity. First, the TET1 enzyme is incubated with the methylated substrate for two hours. Then the primary antibody is added. Next, the plate is treated with an HRP-labeled secondary antibody. Finally, the HRP substrate is added to produce chemiluminescence that can be measured using a chemiluminescence reader.
