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.
