产品介绍 The PRMT4 Homogeneous Assay Kit is designed to measure PRMT4 activity for screening and profiling applications. PRMT4 (CARM1) is an arginine methyltransferase and dual functional coregulator that facilitates transcription initiation by methylation of Arg17 and Arg26 of histone H3. The PRMT4 Homogeneous Assay Kit comes in a convenient AlphaLISA® format, with His-tagged PRMT4 substrate, primary antibody, methylation assay buffer, and purified PRMT4 for 384 enzyme reactions. The key to the PRMT4 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 PRMT4 enzyme is incubated with the substrate. Next, acceptor beads and primary antibody are added, then donor beads, followed by reading the Alpha-counts.
