Figure 2. Inhibition of proline transport by different amino acids.
Proline transport into 40 μg of crude synaptosomal fraction (P3 pellet) was measured in the presence of 10 mM MeAIB and 10 mM L-amino acid as indicated. Data are expressed as means ± SEM obtained from triplicate samples and confirm previous observations (Broer et al. 2006).
