    • A human myelomonocyte interferon-gamma having a novel polypeptide and carbohydrate chain structure is produced by propagation of an established human myelomonocyte in vitro or after being implanted in a non-human warm-blooded animal or in a diffusion chamber placed inside or outside the body of the animal. The human myelomonocyte may be contacted with an inducer during propagation. A monoclonal antibody specific to the human myelomonocyte interferon-gamma is produced by immunizing a non-human warm-blooded animal with purified human myelomonocyte interferon-gamma as an antigen, recovering an antibody producing cell from the animal and fusing the cell with a myeloma cell to produce a hybrid capable of producing the monoclonal antibody. The human myelomonocyte interferon-gamma can be purified by chromatography with an immobilized anti-human myelomonocyte interferon-gamma antibody such as the monoclonal antibody. The human myelomonocyte interferon-gamma can be used as a prophylactic and therapeutic agent for human interferon-gamma susceptive diseases.
    • 具有新型多肽和碳水化合物链结构的人类单核细胞干扰素-γ通过体外建立的人骨髓单核细胞的繁殖或植入非人温血动物或置于体内或体外的扩散室中产生, 这个动物。 人类骨髓细胞在繁殖过程中可能与诱导物接触。 通过用纯化的人骨髓单核细胞干扰素-γ作为抗原免疫非人温血动物,产生对人骨髓单核细胞干扰素-γ特异性的单克隆抗体,从动物中回收产生抗体的细胞并将细胞与骨髓瘤细胞融合 以产生能够产生单克隆抗体的杂交体。 可通过用固定化的抗人骨髓单核细胞干扰素-γ抗体如单克隆抗体进行色谱纯化人类单核细胞干扰素-γ。 人类单核细胞干扰素-γ可用作人类干扰素-γ敏感性疾病的预防和治疗剂。
