JARID1B (KDM5B) Homogeneous Assay Kit

Catalog #: 50512
Size: 384 reactions
JARID1B, also known as PLU-1 and KDM5B, is a JumonjiC (JmjC) and ARID domain-containing histone lysine demethylase that exhibits demethylation activity toward di- and trimethyl-lysine 4 (H3K4me2/3) on histone H3.
The JARID1B Homogeneous Assay Kit is designed to measure activity of the JARID1B for screening and profiling applications. The key to the JARID1B 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 JARID1B enzyme is incubated with the biotinylated substrate. Next, acceptor beads and primary antibody are added, then donor beads, followed by reading the Alpha-counts.

Supplied As:
The JARID1B Homogeneous Assay Kit comes in a convenient AlphaLISA® format, with biotinylated histone H3 peptide substrate, primary antibody, demethylase assay buffer, and purified JARID1B 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.


Instructions for use:
See assay kit data sheet for detailed protocol.
Storage / Stability:
>6 months at –80°C
Great for studying enzyme kinetics and screening small molecular inhibitors for drug discovery and HTS applications.
