Abstract
This invention relates to a DNA fragment comprising a base sequence encoding a non-A non-B hepatitis-specific antigen polypeptide, said base sequence being obtained using genetic engineering techniques from non-A non-B hepatitis virus RNA which is isolated directly from blood plasma from non-A non-B hepatitis patients, to an expression vector and a transformant for use in the expression of the DNA fragment, to a single strand DNA sequence for PCR primer, and to use of said polypeptide and said single strand DNA sequence in the detection of the non-A non-B hepatitis virus. The recombinant polypeptide and the single strand DNA sequence for PCR primer make it possible to detect the non-A non-B hepatitis virus with extremely high accuracy.
