| | Fluorescence Polarization Anisotropy (FPA) Assay |
| Description: | A fluorescence polarization anisotropy (FPA) assay that measures the displacement of either a FITC-labeled MLL-derived peptide or a more potent 10mer-Thr-FAM probe in response to compound treatmen. The assay is run in 384-well format and is read on a BioTek Cytation. Compounds are run as 2 replicates on the left and right sides of the plate; therefore a plate can accommodate 16 compounds in a 10-point, 3-fold dilution scheme, plus positive and negative controls. Replicate values are fit to a 4-parameter fit in XLFit to generate a single IC50 value for each compound that is then converted to a Ki value. Experiments are repeated to generate a 2nd, independent Ki value; values from the two experiments are averaged to produce the reported Ki value for the compound. The assay performs with an average Z′ value of 0.7, and is tolerant of up to 5% DMSO. |
