Abstract:
Assays utilizing Sf9 insect membrane preparations are widely used to study drug-ABC transporter interactions. Sf9 cells show lower glycosylation of proteins and differences in membrane composition when compared to mammalian cells. We investigated the effect of these differences using different BCRP expression systems and biochemical modification of membrane preparations. We found that modification of the membrane lipid composition markedly changed the activity of the BCRP transporter.
