Popis: Covalent binding of PEG to proteins leads to conjugates widely investigated in several biotechnological processes. Their use as pharmaceuticals requires both careful purification and proper characterization. In this context, this paper examines the potentialities offered by hydrophobic interaction chromatography and compares aqueous potassium fluoride and ammonium sulfate as the eluents. Relative contribution of the various forces which dictate the chromatographic behaviour of PEG–protein adducts on Fractogel TSK–Butyl 650 is discussed.
