Scatchard plots of naproxen (a), warfarin (b), and digitoxin (c) binding in various albumin solutions Scatchard plots of naproxen (a), warfarin (b), and digitoxin (c) binding in native human serum, defatted human albumin from Sigma, and three pharmaceutical-grade solutions from Baxter/Immuno, Octapharma, and Pharmacia & Upjohn. The symbols are given in separate box. The albumin solutions contained 0.615 mmol/L albumin. The experiments were performed with ultrafiltration and the results of the calculated parameters are found in table 2.
