Products from BPS Bioscience require a minimum order value above 400€
Applications: Great for studying enzyme kinetics and HTS applications.
Contraindications: 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.
Description: The FBXL10 (KDM2B) Homogeneous Assay Kit is designed to measure the activity of the FBXL10 for screening and profiling applications. FBXL10, also known as KDM2B, JHDM1B, and CXXC2, is a histone lysine demethylase that exhibits demethylation activity toward trimethyl-lysine 4 (H3K4me3) and dimethyl-lysine 36 (H3K36me2) on histone H3. The key to the FBXL10 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 FBXL10 enzyme is incubated with the biotinylated substrate. Next, acceptor beads and primary antibody are added, then donor beads, followed by reading the Alpha-counts.
Storage Stability: At least one year from date of receipt when stored as directed.
Warnings: Avoid multiple freeze/thaw cycles.
Biosafety Level: Not applicable (BSL-1)
