| Description: | FGFR1: In a final reaction volume of 30 μL, FGFR1 (h) (25 ng/ml) is incubated with 50 mM HEPES pH 7.5, 6 mM MnCl2, 1 mM DTT, 0.1 mM Na3VO4, 0.01% Triton-X-100, 500 nM Btn-Flt3 and 5 μM ATP in the presence of compound (1% DMSO final). After incubation for 60 minutes at room temperature the reaction is stopped with 2.27 nM EU-anti P-Tyr, 7 mM EDTA, 31.25 nM SA-XL-665 and 0.02% BSA which is present for 60 minutes at room temperature. Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) signal (ex340 nm. Em 620 nm, em 655 nm) is measured afterwards and results are expressed in RFU (Relative Fluorescence Units). In this assay, the inhibitory effect of different compound concentrations (range 10 μM to 0.1 nM) is determined and used to calculate an IC50 (M) and pIC50 (−log IC50) value. |
