| | Luciferin-Luciferase Assay |
| Description: | The activity of ROCKII (1-543) kinase was measured utilizing Cambrex PKLight ATP Detection Reagent, a homogeneous assay technology using luciferin-luciferase to quantify residual ATP. The assay was performed in 384-well low-volume, white, non- binding surface micro titer plates (Corning). The assay buffer was 25 mM HEPES, pH 7.5, 10 mM MgCl2, 50 mM KC1, 0.2% BSA, 0.01% CHAPS, 100 uM Na3VO4 and 0.5 mM DTT. Test compounds, dissolved in neat DMSO at 500 ug/mL, were serially diluted for dose response for a final starting concentration of 3 ug/mL in 1% DMSO of assay buffer. ROCKII (1-543) (62,408Da) was diluted in assay buffer to a final concentration of 7.5 nM in a total volume of 15 ul. Positive controls were reaction mixtures containing no test compound; negative controls (blanks) were reaction mixtures containing no kinase. |
