title: Improved large scale purification procedure of natural human fibroblast interferon.
abstract: Human fibroblast interferon, produced in tissue culture by a superinduction procedure, was purified 10,000-fold by chromatography to ca 50% purity as judged by SDS-PAGE. The specific activity of the interferon preparation is 2 X 10(8) and the yield is 70%. The interferon preparation is suitable for clinical use.
