The PRMT9 Homogeneous Assay Kit is designed to measure PRMT9 activity for screening and profiling applications. PRMT9 is a histone methyltransferase that exhibits methylation activity toward an arginine residue of SAP145. The PRMT9 Homogeneous Assay Kit comes in a convenient AlphaLISA® format, with GST-tagged PRMT9 substrate, primary antibody, methylation assay buffer, and purified PRMT9 for 384 enzyme reactions.

The key to the PRMT9 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 PRMT9 enzyme is incubated with the substrate. Next, acceptor beads and primary antibody are added, then donor beads, followed by reading the Alpha-counts.

Green and blue dyes that absorb light in the AlphaScreen® signal emission range (520-620 nm), such as Trypan Blue. Avoid the use of the potent singlet oxygen quenchers such as sodium azide (NaN3) or metal ions (Fe2+, Fe3+, Cu2+, Zn2+ and Ni2+). The presence of >1% RPMI 1640 culture medium leads to a signal reduction due to the presence of excess biotin and iron in this medium. MEM, which lacks these components, does not affect AlphaScreen® assays.

COMPONENTS:

See assay kit data sheet for detailed protocol.

12 months from date of receipt, when stored as directed. Kit components require different storage conditions. Be sure to store each component at the proper temperature upon arrival.

Great for studying enzyme kinetics and HTS applications.
