摘要：
The surface structure of finely dispersed iron (FDI) activated by 1,6-hexamethylene diisocyanate and that of resultant FDI with immobilized recombinant human alpha-interferon was examined by X-ray photoelectron spectroscopy (XPS). The organization of protein at the surface layer rather than the amount or thickness of protein films was shown to play a key part in the activity of immobilized interferon. The orientation of immobilized protein molecules in self magnetic field at the FDI surface was suggested to stabilize interferon activity.
