KMT6B, EZH, Retinoblastoma Binding Protein 4 (RBBP4)

50 µl reaction mix (20 mM phosphate pH 7.4, 0.05% Tween-20, 40 µM S-adenosylmethionine, and enzyme complex) add to the wells coated with the substrate on a Neutravidin white plate (G-Biosciences). Incubate for 1 hr. Add antibody against methylated K27 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, 200 mM imidazole, and 20% glycerol.

Aqueous buffer solution

>6 months at –80°C

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