Vincent A. Fischetti has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Streptococcal immunoglobulin a binding protein encoded by emmL2.2
    Patent number: 5352588
    Abstract: The subject invention concerns a novel polynucleotide sequence cloned from emm2.2 gene of a Group A streptococcus, Type II strain which codes for an IgA-binding protein, ML2.2. A process for producing the protein is given. The invention also concerns the protein in an immunoadsorbent and as a tracer for use in measuring and purifying IgA. Kits are given comprising the immunoadsorbent and the tracer form of the protein.

  • Production of streptococcal m protein immunogens and molecular probes
    Patent number: 4784948
    Abstract: Methods and compositions are provided for the cloning and expression of Streptococcus pyogenes M protein genes, and, in particular, types 5, 6 and 24 genes in single-cell host organisms. The streptococcal M protein produced by the recombinant DNA techniques described herein may be formulated for use as immunogens in vaccines to protect against S. pyogenes infections. The gene for the M protein may further be employed as a molecular probe for the accurate identification of streptococci in infected body tissues and fluids.
