The present invention relates to biomedicine engineering technology, and is the gene cloning of polyepitope antigen of hepatitis C virus hcvme and the coded polyepitope antigen HCVME. The hcvme includes 9 epitope genes of HVR1 simulating B cell and 4 epitope genes of T cell in E2 region of HCV genome, and the 4 epitope genes of T cell includes 2 of conservative CTL epitope in region C, 1 of conservative CTL epitope in region NS3 and 1 of conservative Th epitope in region NS3. Serial tests show that hcvme has high cross reaction with karyogamy expressed product GST-HCVME of gst gene and positive hepatitis C antibody serum, and the GST-HCVME immunized male rabbit serum has high distinction frequency on natural HVR1 synthetic peptide. Therefore, hcvme and its expressing product HCVME may be used in preparing nucleic acid vaccine and polypeptide vaccine for hepatitis C and the test reagent for HCV antigen and antibody.

The invention relates to a breeding method of colourful rabbits. The method comprises the following steps of: (1) breeding a pure breeding colourful rabbit for four generations to generate special strains, and selecting a colour male rabbit from the special strains; (2) selecting a female rabbit from white rabbits; and (3) crossbreeding the selected colour male rabbit and female rabbit to generate offspring which have the hair colour of the colourful rabbits, and thus obtaining the colourful rabbits which have the hair colour of the colourful rabbits and uniform hair colour. In the method, the colourful rabbit is crossbred with the white rabbit with excellent production property and the colourful hair colour gene of the rabbit is dominant to the white gene, so the hair colour of the generated offspring accords with that of the colourful rabbit and is uniform. At the same time, because white rabbit has excellent production property, the rabbits with high-quality skin can be generated, the meat production property due to hybrid advantages can be improved and the added value of the rabbit skin is improved.

The invention provides a high-production-performance black meat rabbit new strain breeding method.
