Figure 3. Analysis of para-²¹¹At-phenylalanine (PA) transport by L-type amino acid transporter-1 (LAT1) and LAT2.

Para-²¹¹At-PA uptake by control oocytes (black square) and oocytes expressing LAT1 (black circle) or LAT2 (white circle) in choline buffer was measured for 5, 15, and 45 min. The uptake rates are expressed as mean values ± standard errors of the means (n = 9–11; ^** p < 0.01 in a comparison between LAT1 and LAT2).
