| | MYLK/MLCK Assay |
| Description: | MYLK dissociation constants (Kd) for compounds were determined using the DiscoverX KdELECT platform. The MYLK kinase (accession number NP_444254.3) was labeled with a DNA tag for subsequent qPCR readout while a known active site binding ligand (staurosporine) was immobilized on a solid support (beads). Test compounds were prepared as 111X stocks in 100% DMSO and Kds were determined using an 11-point 3-fold compound dilution series with three DMSO control points. The compounds were then diluted directly into the assays such that the final concentration of DMSO was 0.9%. The assay plates were incubated at room temperature with shaking for 1 hour to equilibrate. The affinity beads were washed (lx PBS, 0.05% Tween 20) to remove unbound kinase and quantify MYLK captured on solid support by qPCR. The Kd was determined by measuring the amount of MYLK captured on the solid support as a function of the test compound concentration. The Kd values were calculated by fitting dose-response curves to the Hill binding equation using the Levenberg-Marquardt algorithm. |
