A method for the production and purification of human tumor necrosis factor (hTNF) is described. This purified material, shows growth inhibitory, hemorrhagic necrosis, cytotoxicity, and cytostasis effects on a variety of human tumors and cancers. The hTNF is free of exogeneous endotoxin, bacteria, and serum factors, hTNF has a molecular weight of about 70,000 hTNF and human interferon used together have a far greater growth inhibitory or cytotoxic effect on human tumors than the sum of their separate effects. The effect is synergistic and is seen with alpha-, beta- or gamma-IFN and with natural and recombinant IFN. |
