Fig. 1From: Characteristics of L-citrulline transport through blood-brain barrier in the brain capillary endothelial cell line (TR-BBB cells)Time-course of [14C]L-citrulline uptake by TR-BBB cells. [14C]L-citrulline (44.4 μM) uptake was performed at 37 °C in ECF buffer. Each point represents the mean ± S.E.M. (n = 3–4)Back to article page
