| Description: | Test compounds were serially diluted in DMSO and then spiked (2 μL) into in 0.4 mL KHB buffer containing wild-type or OCT2-transfected cells and incubated for 10 minutes. Assay was initiated with the addition of 0.1 mL of 100 μM 14C-TEA in KHB buffer (20 μM final concentration after mixing). The concentration of TEA is based on the Km. After 10 minutes of incubation, the assay mixture was quenched with addition of 0.5 mL of ice-cold IX PBS buffer. Samples were then centrifuged at 1000 rpm for 5 min and supernatants were removed. Wash steps were repeated four times with ice-cold PBS. |
