  • Process for recovering interferon
    Patent number: 4526782
    Abstract: Interferon can be recovered simply by contacting an aqueous solution containing interferon which is induced and produced from cells of human origin capable of producing interferon, with a siliceous substance to adsorb interferon on it and eluting the adsorbed interferon with an aqueous solution containing a nonionic surfactant, preferably further containing an acriflavine such as acrinol.

  • Process for recovering interferon
    Patent number: 4343736
    Abstract: A process for recovering interferon which comprises contacting a solution containing an interferon produced by the induced cells of human origin with a water-insolubilized sulfated polysaccharide to allow the interferon to be adsorbed on the water-insolubilized sulfated polysaccharide and then selectively eluting the interferon with an aqueous solution of an inorganic salt.
