Abstract RU 2073719 C1

FIELD: molecular biology, biotechnology. SUBSTANCE: invention relates to preparing DNA fragment HC 250 that determines synthesis of polypeptide showing properties of human hepatitis C virus protein NS3. Polypeptide is prepared using the strain of bacterium Escherichia coli transformed with plasmid carrying DNA fragment HC 250. This polypeptide is able to bind antibodies to gene-encoding protein NS3 of hepatitis C virus. Invention is used in immunodiagnosis of human hepatitis C virus. EFFECT: improved method of preparing. 3 cl
