Notes
50 ul reaction mix (50 mM Tris pH 8.8, 5 mM MgCl2, 4 mM DTT, 0.05% Tween-20, 40 uM 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.
