背景介绍 PRMT3 is a histone methyltransferase that exhibits methylation activity toward H4-R3. 产品介绍 The PRMT3 Direct Activity Chemiluminescent Assay kit is designed to measure PRMT3 activity for screening and profiling applications. The key to the PRMT3 Direct Activity 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, Sadenosylmethionine 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.
