| Number | Title | Issue Date |
| 4490289 | Homogeneous human interleukin 2 Human interleukin 2 (IL-2) derived from induced human malignant cells has been purified to homogeneity using multiple high performance liquid chromatography (HPLC) steps. The purified IL-2 exhibits potent activity promoting the long-term in vitro culture ... | 12/25/1984 |
| 4473642 | Constitutive production of interleukin 2 by a T cell hybridoma A process for constitutively producing murine IL-2 from hybridoma cells generated by fusing mitogen stimulated malignant murine cells with drug sensitive murine thymoma driver cells. A fusing agent is used to fuse the two parent cells together. After fusi... | 09/25/1984 |
| 4464355 | Serum-free and mitogen-free T-cell growth factor and process for making same A serum-free and mitogen-free T-cell growth factor which is effective in stimulating natural killer cell function in tumor patients is provided. A method of producing the growth factor from human, bovine or porcine spleen or blood is described.... | 08/07/1984 |
| 4457916 | Method for stabilizing Tumor Necrosis Factor and a stable aqueous solution or powder containing the same A method for stabilizing Tumor Necrosis Factor (TNF), which comprises adding a stabilizing agent selected from a nonionic surfactant, at least one substance selected from the group consisting of D-glucose, D-galactose, D-xylose, D-glucuronic acid, a salt ... | 07/03/1984 |
| 4448879 | High yield process for in vitro production of serum-free and mitogen-free interleukin-2 An improved in vitro cell culture process for producing in high yield and purity a serum-free and mitogen-free interleukin-2-containing conditioned supernatant. The incubation steps during stimulation and conditioning of the interleukin-2 producing cells ... | 05/15/1984 |
| 4447355 | Method for stabilizing a tumor necrosis factor and a stable aqueous solution or powder containing the same A method for stabilizing a Tumor Necrosis Factor (TNF), which comprises adding at least one member selected from the group consisting of an albumin, a gelatin, a globulin, a protamine and a salt of protamine to an aqueous solution or powder containing TNF... | 05/08/1984 |
| 4438032 | Unique T-lymphocyte line and products derived therefrom Human T-lymphoblast cell line, Proteinaceous products produced therefrom, messenger RNA and DNA expressing the proteinaceous products. A human T-lymphoblast cell line (Mo) maintained as a continuous culture constitutively produces proteins, including immu... | 03/20/1984 |
| 4420395 | Blood purification device Treatment of the blood by means of a blood purification device comprising packed, substantially spherical, smooth-surfaced, porous granules having at least 0.1 μmole/m2 of the silanol group on the surface thereof, a blood inlet and a blood out... | 12/13/1983 |
| 4411993 | Hybridoma antibody which inhibits interleukin 2 activity A process for producing anti-IL-2 antibody from hybridoma cells generated by fusing activated, IL-2 immunized, murine lymphocyte cells with neoplastic murine myeloma cells. Fusion is accomplished by mixing the two cell lines together in the presence of a ... | 10/25/1983 |
| 4406830 | Regulatory glycoprotein for immune response and the use thereof in the production of T-cell growth factor A cell mediated immune response system glycoprotein having a molecular weight of about 90,000 and having at least one sialic acid moiety as a biologically active site is disclosed. The glycoprotein is specifically bound by wheat germ agglutinin and also b... | 09/27/1983 |
| 4404280 | Process for preparing murine interleukin 2 in the presence of interleukin 1 from an interleukin 2 nonproducer malignant cell line and cell line therefor A process for producing murine IL-2 from malignant neoplastic cells which are incapable of IL-2 production by mitogen stimulation alone includes culturing murine leukemia or lymphoma cells in vitro in a protein-containing medium supplemented with various ... | 09/13/1983 |
| 4401756 | Process for preparing human interleukin 2 A process for preparing IL-2 from human malignant cells includes culturing human leukemia or lymphoma cells in vitro in a serum containing medium supplemented with various additives. The culture is stimulated by an optimum concentration of a T cell mitoge... | 08/30/1983 |
| 4390623 | Serum-free and mitogen-free T-cell growth factor and process for making same A serum-free and mitogen-free T-cell growth factor (interleukin-2) preparation is prepared from human, bovine, or procine peripheral mononuclear blood cells which are washed several times with a liquid tissue culture medium and then stimulated in a tissue... | 06/28/1983 |
