| Cell Assay |
CHO cells are stably transfected with expression plasmids encoding human V1a and grown in F-12 K, containing 10% fetal bovine serum, 1% penicillin-streptomycin, 1% glutamate, and 200 μg/mL geneticin at 37 °C in a 10% CO2 incubator at 95% humidity. Cells are plated for 24 h at 50,000 cells/well in clear bottomed 96 well plates and are dye loaded for 60 min with 2 μM Fluo-4-AM in assay buffer. After cell washing, the plate is loaded on a fluorometricimaging plate reader, compound dilution series added to the cells, and agonist activity measured[1].
