Interferon (IFN)-gamma was produced with a high yield in cultures of human peripheral mononuclear cells by combined stimulation with OK-432 and staphylococcal enterotoxin B. Human mononuclear cells cultured in serum-free medium produced several times as much IFN as those in RPMI-1640 medium containing 10% fetal bovine serum. A synergistic effect of OK-432 and staphylococcal enterotoxin B on the production of IFN-gamma was demonstrated. Ultrogel AcA54 column chromatography of crude IFN showed a single peak with an apparent molecular weight of 43,000. Our production system for human IFN-gamma offers a feasible approach to preparation of large quantities of purified IFN-gamma for structure studies, antibody production, and clinical applications.
通过OK-432和葡萄球菌肠毒素B联合刺激,人外周血单个核细胞培养物中可高产干扰素(IFN)-γ。在无血清培养基中培养的人单核细胞产生的IFN是含10%胎牛血清的RPMI-1640培养基中培养的细胞的几倍。证实了OK-432和葡萄球菌肠毒素B对IFN-γ产生具有协同作用。粗制IFN的Ultrogel AcA54柱层析显示一个单峰,表观分子量为43,000。我们的人IFN-γ生产系统为大量制备纯化的IFN-γ用于结构研究、抗体生产和临床应用提供了一种可行的方法。
