Species
Human
Application
Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling
Notes
50 ul reaction mix (20 mM phosphate pH 7.4, 0.05% Tween-20, 40 uM S-adenosylmethionine, and enzyme complex) add to the wells coated with the substrate on a Neutravidin white plate (G-Biosciences). Incubate for 1hr. 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.
