摘要:
The present invention provides a method for highly producing a recombinant protein in a plant storage organ and a GLP-1 derivative. The plant storage organ in which the recombinant protein is highly produced is obtained by transformation with the use of a vector which comprises a recombinant protein gene, a cytokinin-related gene, a drug-resistant gene and a removable DNA element, in which the oytohinin-related gene and the drug-resistant gene exist in the positions so that they can behave together with the DNA element, while the recombinant protein to be expressed in the plant storage organ exists in the position so that it would not behave together with the DNA element. The GLP-1 is produced by using the method, and a derivative having been stabilized against enzymatic digestion is further provided.

There are disclosed a cDNA of human hepatitis C virus gene, its clone and use thereof. The cDNA is prepared by constructing a cDNA library with an RNA, as a template, derived from a liver tissue or serum of a patient who was definitely diagnosed as infected with hepatitis C, carrying out a cDNA cloning with use of the library and probes encoding parts of nucleotide sequence which codes a known HCV virus gene to obtain clones reacting with the probes, carrying out further cloning with use of the reacted clones, determining a nucleotide sequence on each positive clone, and ligating peptides with the nucleotide sequence to establish as only one HCV clone. The HCV clone is constructed with about 9500 nucleotides having a sequence shown in the Sequence Listing.
