| Description: | Inositol monophosphate (IP1) production were measured in 1321N1 cells stably expressing human PAR2 using an IP-One HTRF assay kit (Cisbio). 80 nl of compound in 100% DMSO were added in white small-volume 384-well plates using an Echo 555 (Labcyte) and were incubate for 30 min at 37° C. with 4 μl of cells (15,000 cells per well) in stimulation buffer (HBSS with 20 mM HEPES, pH 7.4). IP1 production was initiated by addition of 4 μl of 140 μM SLIGRL-NH2 (SEQ ID NO.: 4) in stimulation buffer supplemented with 100 mM LiCl. After 60 min at 37° C. cells were lysed and IP1 concentrations were detected according to the manufacturers protocol (Cisbio). Data were normalized to IP1 concentrations using a IP1 standard curve according to the manufacturers protocol (Cisbio). |
