  • Technique for joining amino acid sequences and novel composition useful in immunoassays
    Patent number: 5840834
    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.

  • Assay for equine infectious anemia virus
    Patent number: 5427907
    Abstract: The present invention is directed toward the use of a synthetic peptide as the antigen in an immunoassay for the detection of antibodies against the equine infectious anemia virus in the serum of horses. The synthetic peptide corresponds to the amino acid sequence of an antigenic portion of the GP-45 envelope protein of the equine infectious anemia virus. The immunoassay may be a direct second antibody immunoassay, a one or two step sandwich immunoassay, or a competitive immunoassay.
