Binding
Enzymatic Assay: Compounds were tested in an enzymatic assay using human ERK-2 (Mitogen Activated Kinase 1), recombinantly expressed as an n-terminal 6-His fusion protein in E. coli and corresponding to aa 8-360. The substrate used was the fluorescent Omnia peptide S/T17 (Invitrogen of Carlsbad, Calif.; Cat. KNZ1171C). Test compounds were diluted in DMSO in 3-fold serial dilutions at 100× final concentrations. In addition to compound, the assay contained 50 mM HEPES [pH 7.3], 10 mM MgCl2, 2 mM DTT, 0.005% Triton-X100, 5 nM ERK-2 enzyme, 6.25 μM S/T17 peptide substrate and 25 μM ATP (corresponding to the observed Km) for a total reaction volume of 25 μL. The assay was run at ambient temperature in a white 384-well polypropylene plate (Nunc, Inc of Naperville, Ill.; Cat. 267462) collecting data every 50 seconds for approximately 30 minutes on an Envision plate reader (PerkinElmer, Inc. of Waltham, Mass.); Excitation 340 nm/Emission 495 nm.
