    摘要: The present invention provides for crystalline zinc-interferon alfa-2 (IFN .alpha.-2) having a monoclinic morphology. The present invention further provides for crystalline cobalt-IFN .alpha.-2, crystalline calcium-IFN .alpha.-2, and crystalline IFN .alpha.-2 having a serum half-life of at least about 12 hours when injected into a primate. The present invention further provides for a method for producing a crystalline IFN .alpha.-2 comprising forming a soluble metal-IFN .alpha.-2 complex, and equilibrating the soluble metal-IFN .alpha.-2 complex in solution with an acetate salt of the metal under conditions that will cause the metal-IFN .alpha.-2 solution to become supersaturated and form crystalline metal-IFN .alpha.-2. The present invention also includes crystalline metal-alfa interferon having monoclinic, plate and needle morphologies.
