| | Vasopressin V1B Receptor Antagonist Assay |
| Description: | The purpose of the assay is to determine the inhibitory effect of synthesized compounds on the Vasopressin V1b receptor. The assay was performed in Chinese Hamster Ovary (CHO) cells expressing the human Arginine Vasopressin Receptor 1b (AVPR1b). Arginine Vasopressin (AVP) evokes an increase in intracellular calcium in CHO-AVPR1b cells which is measured in a fluorescence assay on the FLIPRTETRA using calcium sensitive dyes. Test compounds were assessed for their ability to affect the magnitude of the response to AVP, with antagonists showing a concentration-dependent reduction in the AVP-mediated fluorescence.CHO-AVPR1b cells were maintained in routine culture in T175 Flasks at 37° C., 5% CO2. The growth medium consisted of Ham's F12 media supplemented with 10% v/v fetal bovine serum, 1× non-essential amino acids, and 0.4 mg/ml Geneticin G418. |
