Immunogen Region
130-end
Tag
N-terminal FLAG-tag
Formulation
45 mM Tris-HCl, pH 8.0, 124 mM NaCl, 2.4 mM KCl, 90 ug/ml FLAG peptide, 10% glycerol, and 3 mM DTT.
Species
Human
Application
Useful in conjunction with E1 and E2 for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
Notes
50 ul reaction mix (4 mM ATP, 5 mM MgCl2, 1 mM DTT, E1 (0.5 ug), E2 (2.8 ug), Biotin-Ubiquitin (0.5 ug) and SMURF2 (0-2 ug) in 50 mM Tris pH 7.4) incubate for 30 min. at 37°C, then add to streptavidin coated plates and incubate for 30 min at 37°C. Add antibody against SMURF2, incubate 1 hr. Finally, incubate 1 hr. with the Europium-labeled secondary antibody. Time resolved fluorescence measured at room temperature (lambdaexc=330 nm, lambdaem=620 nm).
