    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: Highly purified type B hepatitis antigen (HB Ag) is produced from fluid blood material containing such antigen by subjecting blood material containing naturally occurring HB Ag to a double precipitation with polyethylene glycol. In each precipitation, the pH of the fluid blood material is maintained at approximately 4.4 to 4.7 and a polyethylene glycol concentration of approximately 4.0 to 4.5 weight per cent is used. Particularly good results are obtained if the temperature of the material is maintained in the range of 0.degree. to 8.degree.C after the polyethylene glycol has been added. The antigen thus obtained may be further purified by absorption of impurities to hydroxy apatite, followed by isopycnic banding and zonal ultracentrifugation. Hydroxy apatite column chromatography is used to separate the purified antigen into three separate populations of particles.
