Applications of Inside-Out Vesicle Uptake Assay to Assess the Inhibitory Effects of Various Drugs on Human MRP2 and Rat Mrp2 Transporters
Human MRP2 and rat Mrp2 inside-out vesicles were prepared from Spodoptera frugiperda (Sf9) insect cells expressing the corresponding transporters. MRP2 mediated and ATP dependent uptake of 3H-LTC4 was conducted using the rapid filtration system in the absence or presence of MgATP.
