Figure 6. Uptake of l-[³H]arginine in BAECs and BBECs.

Cells were incubated with l-[³H]arginine for 15 min at 37°C, and the incorporated l-[³H]arginine was measured as described in Methods. Results are shown as radioactive disintegrations per minute (d.p.m.) per μg cell protein (mean ±s.e.m., n = 5). **P < 0.01vs. BAECs.
