Application

Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.

General description

Human JMJD2B, also known as JHDM3B and KDM4B (GenBank Accession No. NM_015015), amino acids 2-500 with N-terminal GST-tag, MW=83 kDa, expressed in Sf9 cells using a Baculovirus expression system.

Physical form

Formulated in: 40 mM Tris-HCl, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 3 mM DTT, 20% Glycerol.

Specificity

0.32 pmole/min/µg Assay conditions: 10µl reaction mix containing assay buffer with 20 mM HEPES (pH 7.4), 50 mM NaCl, 1mM TCEP, 500 µM a-ketoglutarate, 25 µM iron, 2mM ascorbic acid, 0.01% Tween20, 0.5 µM biotinylated peptide substrate, and JMJD2B (2 – 10ng) added to the wells. Add antibody against di-methylated K9 peptide. Incubate for 30 min, then Streptavidin conjugated secondary antibody followed by Alpha Screening detection.

Storage and Stability

At least 6 months at –80°C. Avoid freeze/thaw cycles. Storing diluted enzyme is not recommended, if necessary, use carrier protein (BSA 0.1 – 0.5%).
