Substrate accumulation rate in 10⁶ substrate molecules embryo⁻¹ s⁻¹ (means ± s.d.) for the transporter substrates CAM (diamonds), BFLV (squares) and CROAM (circles). In addition to the indicated MK571 dosage, CAM and CROAM experiments were co-incubated with 2.0 μmol l⁻¹ PSC833 and BFLV experiments were co-incubated with 1.0 μmol l⁻¹ PSC833.
