Kinetic parameters of the uptake of rosuvastatin in OATP1B1-, OATP1B3-, and OATP2B1-expressing HEK293 cells
Data shown in Fig. 2 were used to determine the Km, Vmax, and Pdif values. These parameters were determined by fitting the data using the nonlinear least-squares method. Each point represents the mean ± computer-calculated S.D. (n = 6).
Transporter | Km | Vmax | Pdif |
---|---|---|---|
μM | pmol/min/mg | μl/min/mg | |
OATP1B1 | 0.802 ± 0.274 | 2.11 ± 0.59 | 1.27 ± 0.07 |
OATP1B3 | 14.2 ± 2.8 | 120 ± 25 | 3.00 ± 0.30 |
OATP2B1 | 6.42 ± 1.03 | 32.2 ± 4.9 | 1.12 ± 0.10 |
