FIELD: biotechnology, genetic engineering. SUBSTANCE: invention proposes new recombinant plasmid p280 GM containing gene for granulocyte-macrophage colony-stimulating factor that determines constitutive synthesis of polypeptide showing property of human granulocyte-macrophage colony-stimulating factor and the strain of Escherichia coli SG 20050/p280 GM providing the level of expression of this factor about 15% of total cellular protein at density 109 cells/ml that is about 20-30 mg/l cellular suspension. EFFECT: enhanced effectiveness of factor producing. 2 cl, 3 dwg
