IMPROVED ALPHA INTERFERON COMPOSITION AND METHOD FOR ITS PRODUCTION FROM HUMAN PERIPHERAL BLOOD LEUKOCYTES

摘要

This invention provides a novel improved alpha interferon composition characterized by high specific activity, a purity of greater than 95 % and which upon use in humans is further characterized by a substantial reduction in side effects normally associated with alpha interferon compositions. Also provided is a method for large scale production of the composition from human peripheral blood leukocytes. This alpha interferon composition may be used therapeutically in the treatment of cancers and diseases of the immune system and/or viral etiology.
