Transport of [3H]-Gly-Sar (0.02 mmol/L, 3.7 × 104 Bq/mL) in bPepT1-transfected CHO cells in the presence of unlabeled di- (a and b, Met-Met and Gly-Met), tri- (c, Leu-Gly-Gly), and tetrapeptides (d, Met-Gly-Met-Met) at concentrations that ranged from 0.001 to 10 mmol/L for 5 min. Inhibition of Gly-Sar uptake was assayed at pH 6.0. The values are means (n = 4) with their standard errors
