≥122.3 pmole/min/µg

50 μl reaction mix (50 mM Tris pH 8.8, 5 mM MgCl₂, 4 mM DTT, 0.05% Tween-20, 40 μM S-adenosylmethionine, and EHMT1 (0.05 – 0.5 ng)) is added to substrate-coated wells on a Neutravidin black plate (G-Biosciences). Incubate for 1 hr. Add antibody against methylated K9 residue of histone H3, incubate 1 hr. Then, add secondary HRP-labeled antibody and incubate 30 min. Finally, add HRP chemiluminescent substrates and read luminescence.

40 mM Tris-HCl, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 16 mM glutathione, 20% glycerol, and 3 mM DTT

Aqueous buffer solution

>6 months at –80°C

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