  • Title: Immunogenicity of peptide fusions to hepatitis B virus core antigen.
    Author: Stahl SJ, Murray K.
    Journal: Proc Natl Acad Sci U S A; 1989 Aug; 86(16):6283-7. PubMed ID: 2474830.
    Abstract:
    Several gene fusions have been constructed in which coding sequences for antigenic regions of the pre-S sequences of hepatitis B virus, hepatitis B surface antigen, and the envelope protein of human immunodeficiency virus were linked to the 3' end of that for the first 144 residues of hepatitis B core antigen. The sequences were expressed efficiently in Escherichia coli to give stable products that assembled to form particles morphologically similar to hepatitis B core antigen itself. The products exhibited the antigenic and immunogenic characteristics of both the hepatitis B core antigen epitopes and the epitopes carried by the additional sequences, thus illustrating the value of such proteins as immunological reagents and potential vaccines.
