The JMJD2E Homogeneous Assay Kit is designed to measure activity of JMJD2E for screening and profiling applications, using AlphaLISA® technology. The key to the JMJD2E 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 methyltransferase detection. First, a sample containing JMJD2E enzyme is incubated with the biotinylated substrate for two hours. Next, acceptor beads and primary antibody are added, then donor beads, followed by reading the Alphacounts.
Need us to run inhibitor screens or profile your compounds against JMJD2E (KDM4DL)? Check out our Demethylase Screening Services.
Kit comes in a convenient AlphaLISA® format, with a 384-well plate, biotinylated histone H3 peptide substrate, primary antibody, demethylase assay buffer, and purified JMJD2E for 384 enzyme reactions.
JMJD2E, also known as KDM4DL (lysine (K)-specific demethylase 4D-like) is a JmjC-domain protein that exhibits demethylation activity toward H3-K9Me3 and H3-K36Me3.

Contraindications
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.
Warnings
Avoid freeze/thaw cycles.
Disclaimers and Limitations
BPS Bioscience assay kits are validated using the listed components according to our specific protocol. Any deviations to kit components or protocols, such as using different proteins, cell/tissue lysates, or buffers (including using the same component from other commercial sources) will void any warranties on the performance of the assay kit and is not recommended.
End-users should immediately report any issues to [email protected] upon receipt of the kit, such as missing components, damaged vials, no dry ice, etc.
