| Description: | Automated FLIPR (Fluorometric Imaging Plate Reader) technology was used to screen for inhibitors of PDGF-induced increases in intracellular calcium levels in fluorescent dye loaded endothelial cells. NHDF-Ad (Normal Human Dermal Fibroblasts, Adult; Lonza) were seeded in 384-well fibronectin coated black-walled plates overnight @ 37° C./5% CO2. Cells were loaded with calcium indicator Fluo-4 for 45 minutes at 37° C. Cells were washed 2 times (Elx405, Biotek Instruments) to remove extracellular dye. For screening, cells were pre-incubated with test agents for 30 minutes, at a single concentration (10 uM) or at concentrations ranging from 0.0001 to 10.0 uM followed by PDGF-BB stimulation (30 ng/mL). Changes in fluorescence at 516 nm were measured simultaneously in all 384 wells using a cooled CCD camera. Data were generated by determining max-min fluorescence levels for unstimulated, stimulated, and drug treated samples. |
