  • Recovery of functional human leukocytes from recycled filters
    Patent number: 5989441
    Abstract: A method of recovering functional human leukocytes from blood filters used to deplete leukocyte content from leukocyte-containing blood-cell suspensions is provided. More particularly, this method involves isolating leukocytes from filters which have been used to purify red blood cells or platelets in isolation from leukocytes by back-flushing the used filters with a hemolysis solution, such as cold ammonium chloride, and collecting the functional human leukocytes.
    Type: Grant

  • Composition containing human alpha interferon species proteins and method for use thereof
    Patent number: 5676942
    Abstract: This invention provides alpha interferon compositions comprising one or a mixture of selected highly antiviral interferon proteins, which compositions are characterized by increased anti-viral activity. These compositions may be used therapeutically in the treatment of viral infection, particularly retroviral or hepatitis infection or as additives to conventional antiviral agents to increase the antiviral potency thereof.

  • Separation of alpha interferon receptor proteins and antibodies therefor
    Patent number: 5516515
    Abstract: Two distinct alpha interferon receptor proteins have been separated and partially purified by antigen affinity chromatography and SDS-PAGE. These proteins are potentially useful as therapeutic agents. Antibodies against these proteins are potentially useful as diagnostic and therapeutic agents.

  • Alpha interferon composition and method for its production from human peripheral blood leukocytes
    Patent number: 5503828
    Abstract: 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.
