Tag
N-terminal GST-tag
Formulation
40 mM Tris-HCl, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 0.04% Tween-20, 20% glycerol, and 3 mM DTT.
Species
Human
Application
Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling
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 10-100 ng SUV39H1) is added to the wells of a substrate-coated 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.
Avoid freeze/thaw cycles. Storing diluted enzyme is not recommended. If necessary, use carrier protein (BSA 0.1 - 0.5%).
