Luciferase Assay: The stock cultures are grown, at 37° C. and under 5% CO2, in DMEM/F12 medium containing 10% FCS (fetal calf serum) and in each case split 1:10 after 2-3 days. Test cultures are seeded in 384-well plates with 2000 cells per well and grown at 37° C. for approx. 48 hours. The medium is then replaced with a physiological sodium chloride solution (130 mM sodium chloride, 5 mM potassium chloride, 2 mM calcium chloride, 20 mM HEPES, 1 mM magnesium chloride hexahydrate, 5 mM sodium bicarbonate, pH 7.4). The substances to be tested, which are dissolved in DMSO, are pipetted into the test cultures (maximum final concentration of DMSO in the test mixture: 0.5%) in a dilution series of from 5x10-11 M to 3x10-6 M (final concentration). 10 minutes later, forskolin is added to the A1 cells and all the cultures are subsequently incubated at 37° C. for four hours.
