Representative size exclusion profiles of [14C]RSA in urine collected after intravenous administration in PAN (closed circles) and control (open circles) rats.
The same levels of radioactivity in the urine of PAN and controls was loaded onto the column. Identical profiles were obtained at 2 h and 24 h (from n = 5 for each time point). Native [14C]RSA elutes at Kav 0.18. Chromatography was performed on Sephadex G-100.
