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 mitogen to produce a supernate which contains IL-2. After a period of time, the supernate is collected and processed to purify the IL-2. Phorbol myristate acetate may be added to the culture medium to boost production of IL-2. |
