| Description: | It was introduced human URAT1 full-length cDNA into an expression vector pcDNA5 / FRT / V5-His TOPO (registered trademark) (Invitrogen). The resulting expression plasmids, the liposome method using Lipofectamine LTX (Invitrogen), Chinese hamster ovary cells (hereinafter, referred to as CHO cells) was introduced into, by culturing in a selective medium containing hygromycin and human URAT1 stable The expression cell line we were prepared.Human URAT1 expression CHO cells, 10% fetal calf serum, D-MEM / F-12 containing the hygromycin (1: 1) using a mixed medium, 37 C, were cultured in the presence of 5% CO2. Cells were seeded in 96-well plates (Corning Incorporated) in 0.8x10E+5 cells / well, were subjected to the following uric acid transport inhibition test after 24 hours.After removal of the medium by aspiration, sodium gluconate of cells 125mM, potassium gluconate of 4.8mM, potassium dihydrogen phosphate of 1.2mM, magnesium sulfate of 1.2mM, calcium gluconate of 1.3mM, 5. washed once. |
