| Description: | FMS: IC50 values of compounds against FMS kinase were determined by LanthaScreen™ Eu Kinase Binding Assay at Invitrogen (Life Technologies Grand Island, N.Y.) where total reaction volume was 10 μL in low-volume 384-well plates (#4511, Corning). Serially diluted compounds (3-fold) were incubated with kinase (1.25 nM) for 10 min, following which a mixture of ATP (10 μM) (#A1852, Sigma, St-Louis, Mo.) and fluorescent-PolyGT substrate (200 nM) (#PV3610, Invitrogen, Life Technologies Grand Island, N.Y.) was added and incubated in dark at room temperature for 1 h. After 1 h, 10 μL stop solution containing Terbium labeled antibody (4 nM) (#PV3529, Invitrogen, Life Technologies Grand Island, N.Y.) and EDTA (#E5134, Sigma, St-Louis, Mo.) (20 mM) in TR-FRET dilution buffer (#PV3574, Invitrogen, Life Technologies Grand Island, N.Y.) was added. Readings were taken in a Synergy Neo Plate reader (BioTek, Winooski) at single excitation of 340 nm and Dual emission at 495 nm and 520 nm respectively. |
