| Research Abstract |
An attempt was made to establish an antigen antibody assay system associated with non-A, non-B hepatitis. We have established monoclonal antibody from convalescent chimpanzee lymphocytes by EV virus transformation method. We found the corresponding antigen in the chimpanzee liver infected with non-A, non-B hepatitis virus and never found in the liver of the chimpanzees infected hepatitis A and B virus.
However, cDNA coding this antigen hybridized with somatic genome, then this antigen was not coded by the viral genome.
Then we cloned hepatitis C Genome from Japanese donor blood by immunoscreening and sequenced. Sequence of this Japanese clone of HCV is different from Chiron's clone. Hemology is only 74% in region NS5. We established EIA assay system of the antibody against HCV.
And we also established cDNA assay system of HCV genom by PCR method.
