  • Simian virus recombinant that directs the synthesis of hepatitis B surface antigen
    Patent number: 4442205
    Abstract: A process for producing a recombinant between simian virus 40 (SV40) and hepatitis B virus (HBV) is given. When tissue culture cells are infected with the recombinant, hepatitis B surface antigen is produced. Because a single cloned gene is used, the surface antigen produced is homogeneous and can be produced without conventional dependence on human sera. The antigen is excreted into the culture medium as 22 nm particles with the same physical properties, antigenic composition and constituent polypeptides as those found in the sera of patients with Type B hepatitis. The antigen is useful for the preparation of vaccines.
