Products from BPS Bioscience require a minimum order value above 400€
Encompassing Amino Acids: 2-end (all components)
Applications: Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
Assay Conditions: 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 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.
