| FLIPR (Fluorescence Imaging Plate Reader)-Based Ca2+ Assay |
Description: | One day before the assay was performed, human TRPV1 expressed in 1321N1 astrocytoma cells were plated onto 96-well assay plates and grown until 2.5 h before the assay, and the cells were loaded with the Ca2+ reporter dye Fluo3-AM for 2 h at room temperature. After this, the cells were washed, and continuously being incubated for 30 min with medium containing test compounds at a range of different concentrations. The plates were then placed into a FLIPR to monitor fluorescence (excitation @ 488 nm and emission @540 nm) before and after the addition of capsaicin, antagonist potency was determined versus an EC80 concentration of capsaicin that was determined empirically on the day of the experiment. |
