JMJD2B (KDM4B) Homogeneous Assay Kit

Catalog #: 50414
Size: 384 reactions
$1,725
Background:
JMJD2B is a JmjC-domain protein that exhibits demethylation activity toward H3-K9Me3 and H3-K36Me3.
Description:
The JMJD2B Homogeneous Assay Kit is designed to measure activity of the JMJD2B for screening and profiling applications, using AlphaLISA® technology. The key to the JMJD2B 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 JMJD2B enzyme is incubated with the biotinylated substrate. Next, acceptor beads and primary antibody are added, then donor beads, followed by reading the Alpha-counts.
Synonym(s):
JHDM3B, KDM4B
Supplied As:
The JMJD2B Homogeneous Assay Kit comes in a convenient format, with a 384-well plate, biotinylated histone H3 peptide substrate, primary antibody, demethylase assay buffer, and purified JMJD2B 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.
