Abstract
Human fibroblast interferon may be purified to a high degree by using a simple two-step purification method comprising (a) subjecting an aqueous interferon solution to chromatography on porous glass beads, and (b) subjecting the resulting aqueous interferon solution to chromatography on immobilized zinc chelate. Overall recoveries of about 45-76% of the initial interferon activity may be achieved and the end product will be free of any skin reactive agents.
