    摘要: A surface structural protein of Hepatitis A Virus (HAV) has been isolated and characterized from virus grown in tissue culture. This 33,000 dalton viral protein (VP-1) reacts with immune HAV sera and monoclonal antibodies that neutralize HAV infectivity. The VP-1 is usable for the preparation of a polypeptide subunit vaccine for HAV.Hybridoma cells were made which produced monoclonal antibodies to HAV or VP-1. These monoclonal antibodies were found to neutralize the infectivity of HAV and to compete with polyclonal antibody derived from human HAV immune sera. The monoclonal antibodies are useful for the neutralization of infectious HAV, the detection of antibodies to neutralizing sites on HAV, and the diagnoses of HAV disease in humans and other susceptible hosts.

    摘要: Chemically synthesized polypeptides include amino acid residue sequences that substantially correspond to the amino acid residue sequences of T cell and B cell determinant portions of a natural, pathogen-related protein, in particular, a hepatitis B virus surface antigen (HBsAg). When administered to a host alone, as polymers or as carrier-bound conjugates, the polypeptides induce the proliferation of thymus-derived cells in hosts primed against hepatitis B virus.

    摘要: There is disclosed a new synthetic peptide which evokes an immunological response. The synthetic peptide, moreover, interacts with antibodies to hepatitis B surface antigen (HBsAg). Thus, the synthetic peptide is useful as an immunizing agent in a vaccine as an active component thereof where it serves to produce antibodies in vivo which are protective against hepatitis B virus. The synthetic peptide of the invention comprises the following sequence of amino acids: Arg Trp Met Met Leu Arg Arg (I) and preferably has the following sequence: Gly Tyr Arg Trp Met Met Leu Arg Arg Phe Gly (II).

    摘要: Disclosed is an isolated non-A, non-B hepatitis virus genomic cDNA covering the entire region of the virus gene nucleotide sequence from the 1st to 9416th nucleotides shown in FIG. 2(1) through FIG. 2(16) hereof, wherein the coding region is from the 333rd to 9362nd nucleotides, and the 5'- and 3'-noncoding sequences contain 332 nucleotides and 54 nucleotides, respectively. Part of the cDNA and an antigen polypeptide as an expression product thereof are useful as a diagnostic reagent for non-A, non-B hepatitis. The antigen polypeptide is also useful as an active ingredient for a non-A, non-B hepatitis virus vaccine.
