| | Fluorescent Polarization Binding (FP Binding) Assay |
| Description: | Test compounds were serially diluted in DMSO at 100 fold final concentrations in the assay (1% DMSO final). In each well of a 384-well Plate were dispensed 0.1 μL of compound solution (or DMSO for controls) followed by 5 μL of GST-hRIPK1 (8-327) at twice the final concentrations in assay buffer (50 mM HEPES pH 7.5, 10 mM NaCl, 50 mM MgCl2, 0.02% CHAPS, 0.5 mM DTT and 0.01% Pluronic F127). For negative control the enzyme addition was replaced by assay buffer only.After addition of 5 μL of fluorescentlabeled ligand at twice the final concentrations in assay buffer, the plate was incubated at RT for 30 mM. At the end, the binding was measured as FP value with the Envision (PerkinElmer) plate reader using filter for an excitation λ=531 nm FP and an emission λ=595 nm FP (S & P-pol). GST-hRIPK1 (8-327) enzyme was produced via Baculovirus expression. |
