  • Advanced antigen presentation platform
    Patent number: 7279555
    Abstract: The present invention provides particles for the presentation of haptens for the purpose of eliciting an immune response. The amino acid sequences of the monomers which make up the particles are derived from duck hepatitis B virus core protein. The particles may also deliver nucleic acids. The nucleic acids may be delivered for the purpose of enhancing an immune response, or for other purposes such as gene therapy.
    Type: Grant

  • Immunoassay technique using histidine tags, metals, and chelating agents
    Patent number: 5674677
    Abstract: Two amino acid sequences are joined together using an electron acceptor moiety and a linking moiety, such as a chelating agent. In particular, an amino acid sequence specific for binding to a material interest is linked to an enzyme which acts on an indicator, such as a colorimetric, phosphometric, fluorometric or chemiluminescent substrate. The linking composition is useful in immunoassays.

  • Cyclic peptide and method of use for inducing an immunological response to hepatitis B virus
    Patent number: 4778784
    Abstract: A composition for eliciting production of antibody to hepatitis B surface antigen and method of neutralizing the infectivity of hepatitis type B virus. A cyclic polypeptide is prepared having a disulfide bond in a hydrophilic region, namely residues 117-137 or 122-137 and an amino acid sequence unique from that associated with the native 25,000 molecular weight polypeptide derived from hepatitis B surface antigen.
