  • Method for producing human leukocyte interferon alpha-2
    Patent number: 4680260
    Abstract: A method for producing human leukocyte interferon alpha-2 resides in that there is carried out submerged cultivation of a producer strain Pseudomonas species VG-84 carrying a plasmid pVG3 with an inserted gene of human leukocyte interferon alpha-2, said strain being deposited in the collection of microorganism cultures at the USSR Antibiotics Research Institute under Reg. No. 1742; said strain being cultivated in a nutrient medium, containing the sources of carbon and nitrogen, mineral salts and growth stimulants, under aeration in the presence of antibiotics, i.e., streptomycin or tetracycline, or a mixture of both, followed by isolation and purification of the end product.
