| HCRTR1 | Homo sapiens | OX1 ANTA IP1: Activation of the orexin receptors expressed in cell lines results in an increase in intracellular IP3 concentration. IP1, a downstream metabolite of IP3, accumulates in cells following receptor activation and is stable in the presence of LiCl. Using Cisbio™`s HTRF technology with Lumi4TM-Tb cryptate and a suited fluorescence plate reader, this functional response is detectable and quantifiable. | IC50 = 1.600 nM | IC50 = 1.100 µM | ||
| HCRTR2 | Homo sapiens | OX2 ANTA IP2: Activation of the orexin receptors expressed in cell lines results in an increase in intracellular IP3 concentration. IP1, a downstream metabolite of IP3, accumulates in cells following receptor activation and is stable in the presence of LiCl. Using Cisbio™`s HTRF technology with Lumi4TM-Tb cryptate and a suited fluorescence plate reader, this functional response is detectable and quantifiable. | IC50 = 62.600 nM | IC50 = 8.200 µM |
