RECOMBINANT PLASMID DNA ENCODING SYNTHESIS OF HBS AG HEPATITIS VIRUS B, AND A STRAIN OF VACCINE VIRUS - A PRODUCER OF HBS AG HEPATITIS VIRUS B Russian patent published in 1995 - IPC

Abstract SU 1515698 A1

FIELD: biotechnology. SUBSTANCE: recombinant DNA has two adjoining copies of gene of HBs-antigen of hepatitis virus B to which of each protein promoter 7.5 kD of vaccine virus is preceded. Both copies were flanked by the sequences Hind III-J-fragment of vaccine virus DNA. Recombinant strain produces up to 2200 ng HBs Ag/106 cells x 24 h. EFFECT: strain-producer of antigen and recombinant plasmid indicated above. 1 tbl
