Polypeptide antigens are disclosed which are immunoreactive with sera from individuals having a non-A, non-B, non-C, non-D, non-E Hepatitis, herein designated Hepatitis G Virus (HGV). Corresponding genomic-fragment clones containing polynucleotides encoding the open reading frame sequences for the antigenic polypeptides are taught. The antigens are useful in diagnostic methods for detecting the presence of HGV in test subjects. The antigens are also useful in vaccine and antibody preparations. In addition, the entire coding sequences of two HGV isolates are disclosed. Methods are presented for nucleic acid-based detection of HGV in samples and also methods for the isolation of further genomic sequences corresponding to HGV.

Hepatitis G virus and molecular cloning thereof

Polypeptide antigens are disclosed which are immunoreactive with sera from individuals infected with non-A, non-B, non-C, non-D, non-E hepatitis. Also disclosed are corresponding genomic-fragment clones containing polynucleotides encoding the open reading frame sequences for the antigenic polypeptides. The antigens are useful in diagnostic methods for detecting the presence of N-(ABCDE) hepatitis agent infection in primates. The antigens are also useful in vaccine and antibody preparations. Methods are presented for the isolation of entire genomes corresponding to the N-(ABCDE) hepatitis agents.
