Fig. 5.
Binding of DEX in homogenates prepared from male rat liver (left), female rat liver (middle), and male rat lung (right) at initial concentrations of 1 μg/ml (gray) and/or 10 μg/ml (black). Symbols depict the mean ± S.D. of the binding factor (Cbound/Cfree) across four dilutions of tissue homogenate. The dashed line represents the best-fit line extrapolated to an undiluted state of tissue (dil = 1).
