RECOMBINANT PLASMID DNA pFastBac-G2R-IgG, WHICH CONTAINS FRAGMENT OF SMALLPOX VIRUS GENOME, CODING FACTOR OF TUMOUR NECROSIS, BINDING PROTEIN, AND FRAGMENT OF HUMAN GENOME, CODING SECTION OF HEAVY CHAIN OF ANTIBODY G, AND STRAIN OF BACULOVIRUS BvG2RIgG, WHICH PRODUCES SOLUBLE CHIMERIC PROTEIN, WHICH CONSISTS OF SMALLPOX VIRUS PROTEIN, BINDING FACTOR OF TUMOUR NECROSIS, AND FRAGMENT OF HEAVY CHAIN OF HUMAN ANTIBODY G Russian patent published in 2009 - IPC C12N15/62 C12N15/28 C12N15/39 C12N15/86 C12N7/01 

FIELD: medicine.

SUBSTANCE: invention is related to preparation of protein, binding tumour necrosis factor (TNF), and may be used in medicine. Strain-producer of baculovirus BvG2RIgG is created with the help of recombinant plasmid DNA pFastBac-G2R-IgG with size of 6444 p.n. and molecular mass 4.18 mDa, which bears fragment of smallpox virus genome of strain India-1967, which codes protein that binds TNF, and fragment of human genome, which codes fragment of heavy chain of human antibody G. Produced strain produces soluble chimeric protein, which consists of smallpoz virus protein, which binds TNF, and fragment of heavy chain of human antibody G.

EFFECT: wider spectrum of new generation preparations intended for treatment of human diseases related to hyperproduction of tumour necrosis factor.
