G9a Homogeneous Assay Kit

Catalog #: 52051
Size: 384 reactions
G9a is a histone methyltransferase that exhibits methylation activity toward H3-K9.
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.
G9a, EHMT2, KMT1C, euchromatic histone-lysine N-methyltransferase 2
Supplied As:
Kit comes in a convenient AlphaLISA® format, with biotinylated histone H3 peptide substrate, primary antibody, methylation assay buffer, and purified G9a for 384 enzyme reactions.
Avoid 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.


Instructions for use:
See assay kit data sheet for detailed protocol.
Storage / Stability:

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 screening small molecular inhibitors for drug discovery and HTS applications.
