The DNMT3A Direct Activity Assay Kit is designed to measure DNMT3A activity for screening and profiling applications. The key to the DNMT3A Direct Activity Assay Kit is a highly specific antibody that recognizes 5-methylcytosine of the substrate. With this kit, only three simple steps on a microtiter plate are required for detection of DNMT3A activity. First, S-adenosylmethionine is incubated with a sample containing assay buffer and DNMT3A/3L for two hours. Next, primary antibody is added. Finally, the plate is treated with an HRP-labeled secondary antibody followed by addition of the HRP substrate to produce chemiluminescence that can then be measured using a chemiluminescence reader.

The DNMT3B Direct Activity Assay Kit is designed to measure DNMT3B activity for screening and profiling applications. The key to the DNMT3B Direct Activity Assay Kit is a highly specific antibody that recognizes 5-methylcytosine of the substrate. With this kit, only three simple steps on a microtiter plate are required for detection of DNMT3B activity. First, S-adenosylmethionine is incubated with a sample containing assay buffer and DNMT3B/3L for two hours. Next, primary antibody is added. Finally, the plate is treated with an HRP-labeled secondary antibody followed by addition of the HRP substrate to produce chemiluminescence that can then be measured using a chemiluminescence reader.

The DNMT Universal Assay Kit is designed to measure DNMT activity for screening and profiling applications. The key to the DNMT Universal Assay Kit is a highly specific antibody that recognizes 5-methylcytosine on the substrate. With this kit, only three simple steps on a microtiter plate are required for detection of DNMT activity. First, S-adenosylmethionine is incubated with a sample containing assay buffer and DNMT for two hours. Next, primary antibody is added. Finally, the plate is treated with an HRP-labeled secondary antibody followed by addition of the HRP substrate to produce chemiluminescence that can be measured using a chemiluminescence reader.

The PRMT6 Direct Activity Assay kit is designed to measure PRMT6 activity for screening and profiling applications. The key to the PRMT6 Direct Activity Assay Kit is a highly specific antibody that recognizes methylated R3 residue of Histone H4. With this kit, only three simple steps on a microtiter plate are required for methyltransferase detection. First, S-adenosylmethionine is incubated with a sample containing assay buffer and methyltransferase enzyme for one hour. Next, primary antibody is added. Finally, the plate is treated with an HRP-labeled secondary antibody followed by addition of the HRP substrate to produce chemiluminescence that can then be measured using a chemiluminescence reader.

The G9a Homogeneous Assay Kit is designed to measure the activity of G9a (also known as EHMT2 or KMT1C) for screening and profiling applications, using AlphaLISA® technology. The key to the G9a Homogeneous Assay Kit is a highly specific antibody that recognizes methylated substrate. With this kit, only three simple steps on a microtiter plate are required for methyltransferase detection. First, a sample containing G9a enzyme is incubated with the biotinylated substrate for one hour. Next, acceptor beads and primary antibody are added, then donor beads, followed by reading the Alpha-counts.

The PRMT5 Homogeneous Assay Kit is designed to measure PRMT5 activity for screening and profiling applications. PRMT5 is a histone methyltransferase that exhibits methylation activity toward H4-R3. The key to the PRMT5 Homogeneous Assay Kit is a highly specific antibody that recognizes methylated substrate. With this kit, only three simple steps on a microtiter plate are required for methyltransferase detection. First, a sample containing PRMT5 enzyme is incubated with the biotinylated substrate for two hours. Next, acceptor beads and primary antibody are added, then donor beads, followed by reading the Alpha-counts.
