Figure 2
Western immunoblotting (a) and graphical representation of urinary sodium (U-Na) excretion (b) according to exosomal prostasin band intensities. At U-Na>200 mmol l−1, the prostasin values dropped. The values for prostasin were extracted from exosome prostasin immunoblotting at two time points during the morning in six subjects. An equal amount of total urinary exosomal protein extract was loaded per lane (25 μg), and triplicate experiments were performed. AU, arbitrary units. A full color version of this figure is available at the Hypertension Research journal online.
