STRAIN OF YEAST PICHIA PASTORIS PS105(PBIG) AS PRODUCER OF BOVINE INTRACELLULAR IMMUNE INTERFERON, RECOMBINANT PLASMID DNA PBIG PROVIDING BIOSYNTHESIS OF BOVINE INTRACELLULAR IMMUNE INTERFERON AND METHOD FOR CONSTRUCTING RECOMBINANT PLASMID DNA PBIG Russian patent published in 2004 - IPC

Abstract RU 2231545 C1

FIELD: biotechnology, genetic engineering, veterinary science, molecular biology.

SUBSTANCE: invention can be used in microbiological industry and agriculture. Plasmid DNA pBIG providing the biosynthesis of bovine intracellular gamma-interferon is constructed by excision of yeast Saccharomyces cerevisiae gene MFα prepro-region from bacterial-yeast vector pPIC9 with restriction endonucleases Bam HI and Xho I. The yeast strain Pichia pastoris PS105(pBIG) as a producer of bovine intracellular immune interferon is obtained and deposited in All-Russian collection of industrial microorganisms at number VKPM-Y-2990. Application of invention provides preparing the bovine intracellular gamma-interferon with the enhanced yield.

EFFECT: improved preparing method, valuable biological properties of strain.
