| | Luminex Assay |
| Description: | The cellular assay for the determination of the PDK1 kinase activity is carried out as a Luminex assay in the 96-well format. PC3 cells are sown at 20,000 cells per well in 100 ul of medium (45% of RPMI1460/45% of Ham's F12/10% of FCS) and incubated on the following day for 30 min with a serial dilution of the test substance (7 concentrations) under serum-free conditions. The cells are subsequently lysed using 90 ul of lysis buffer (20 mM tris/HCl pH 8.0, 150 mM NaCl, 1% of NP40, 10% of glycerol, 1% of phosphatase inhibitor I, 1% of phosphatase inhibitor II, 0.1% of protease inhibitor cocktail III, 0.01% of benzonase) per well, and the lysates are separated off from insoluble cell constituents by means of centrifugation through a 96-well filter plate (0.65 um). The lysates are incubated overnight at 4° C. with shaking with Luminex beads to which an anti-total PKB antibody is coupled. The detection is carried out on the following day by addition of a phospho-T308-PKB antibody and a species-specific peroxidase-labelled secondary antibody. |
