Uptake of AsIII, MAsIII and SbIII by zebrafish AQP-expression Xenopus oocytes. Various metalloids were added at 1 mM final concentration to oocytes that were injected by cRNA. Oocytes were incubated for 30 min and digested for metalloid quantification. The standard deviation was calculated from three replicates and plotted using Sigma Plot 10 (n = 7 oocytes were used, P < 0.01 calculated from water control and Aqp injected samples). A. Uptake of AsIII. B. Uptake of MAsIII. C. Uptake of SbIII.
