The JHDM1D Homogeneous Assay Kit is designed to measure activity of JHDM1D for screening and profiling applications. JHDM1D, also known as KDM7A and KIAA1718, is a JumonjiC (JmjC) domain-containing histone lysine demethylase that exhibits demethylation activity toward dimethyl-lysine 9 and dimethyl-lysine 27 on histone H3 (H3K9me2 and H3K27me2 respectively). The key to the JHDM1D Homogeneous Assay Kit is a highly specific antibody that recognizes demethylated substrate. With this kit, only three simple steps on a microtiter plate are required for demethylase activity detection. First, a sample containing JHDM1D enzyme is incubated with the biotinylated substrate. Next, acceptor beads and primary antibody are added, then donor beads, followed by reading the Alpha-counts.

The JHDM1D Homogeneous Assay Kit comes in a convenient AlphaLISA® format, with biotinylated histone H3 peptide substrate, primary antibody, demethylase assay buffer, and purified JHDM1D for 384 enzyme reactions.

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 culture medium RPMI 1640 at >1% leads to signal reduction due to the presence of excess biotin and iron in this medium. MEM, which lacks these components, does not affect AlphaScreen assays.

 

See assay kit datasheet for detailed protocol.

At least 6 months from date of receipt when stored as directed.

Great for studying enzyme kinetics and HTS applications.
