The NSD2 Direct Activity Chemiluminescent Assay Kit is designed to measure NSD2 activity for screening and profiling applications. The key to the NSD2 Chemiluminescent Activity Assay Kit is a highly specific antibody that recognizes methylated residue of Histone H3. With this kit, only three simple steps are required for methyltransferase detection. First, S- adenosylmethionine is incubated with a sample containing assay buffer and methyltransferase enzyme. 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.
