for Recombinant JMJD2D / KDM4D proteinContents

Full length recombinant JMJD2D / KDM4D protein is supplied in 25 mM HEPES-NaOH pH 7.5, 300 mM NaCl, 5% glycerol, 0.04% Triton X-100, 0.2 mM TCEP. Please refer to product insert upon arrival for lot-specific concentration.

for Recombinant JMJD2D / KDM4D proteinBackground

KDM4D (lysine (K)-specific demethylase 4D), also known as JMJD2D (Jumonji Domain Containing 2D) is a protein that functions as a histone demethylase that preferentially demethylates di- and trimethylated lysine 9 residues of histone H3, while it has no activity on monomethylated H3K9 residues.

for Recombinant JMJD2D / KDM4D proteinApplication Notes

Recombinant JMJD2D / KDM4D is suitable for use in the study of enzyme kinetics, inhibitor screening, and selectivity profiling.

Histone Demethylase Assay Conditions: 50 mM HEPES pH 7.5, 0.02% Triton X100, 100 μM 2OG, 100 μM Ascorbate, 50 μM (NH4)2Fe(SO4)2·6H2O, 1 mM TCEP, 100 nM Recombinant JMJD2D / KDM4D protein, and 3.3 μM H3K9me3 (aa 1-21) peptide at 2 hours at room temperature. MALDI-TOF was used for detection.
