Fig. 4From: Functional characterization of oligopeptide transporter 1 of dairy cowspH dependency of Gly-Sar uptake in bPepT1-transfected Chinese hamster ovary cells. The transfected cells were incubated with uptake buffer that contained 0.02 mmol/L [3H]-Gly-Sar (3.7 × 104 Bq/mL) at pH 5.0–7.5 for 5 min. The values are means (n = 4) with their standard errors. The means without a common letter are significantly different, P < 0.05Back to article page
