JMJD2E (KDM4DL) Homogeneous Assay Kit

Catalog #: 50417
Size: 384 reactions
$1,725
Background:
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.
Description:
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.
Synonym(s):
JMJD2E, KDM4DL, lysine (K)-specific demethylase 4D-like
Supplied As:
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.
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.

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.

Application(s):
Great for studying enzyme kinetics and screening small molecular inhibitors for drug discovery and HTS applications.

Notes:

The buffer in this kit was reformulated in May of 2015 with a different reducing agent to improve assay performance. The old formulation can still be purchased upon special request.

Warning(s):
Avoid freeze/thaw cycles.
