Patents by Inventor Mark A. Vaeck

Mark A. Vaeck 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).

  • Hybrid gene incorporating a DNA fragment containing a gene coding for an insecticidal protein, plasmids, transformed cyanobacteria expressing such protein and method for use as a biocontrol agent
    Patent number: 5516693
    Abstract: The instant invention is drawn to plasmid p1BN10 harbored in E. coli DSM 4020 and coding for a Bacillus thuringiensis endotoxin (Bt8 toxin) fused in frame to the neo gene of pBR322.
    Type: Grant
    Filed: March 4, 1987
    Date of Patent: May 14, 1996
    Assignee: Board of Trustees operating Michigan State University
    Inventors: Mark A. Vaeck, Wipa Chungjatupornchai, Lee McIntosh
  • Transformation vectors allowing expression of foreign polypeptide endotoxins from Bacillus thuringiensis in plants
    Patent number: 5317096
    Abstract: Novel transformation vectors containing novel chimeric genes allow the introduction of exogenous DNA fragments coding for polypeptide toxins produced by Bacillus thuringiensis or having substantial sequence homology to a gene coding for a polypeptide toxin as described herein and expression of the chimeric gene in plant cells and their progeny after integration into the plant cell genome. Transformed plant cells and their progeny exhibit stably inherited polypeptide toxin expression useful for protecting said plant cells and their progeny against certain insect pests and in controlling said insect pests.
    Type: Grant
    Filed: February 5, 1993
    Date of Patent: May 31, 1994
    Assignee: Plant Genetic Systems, N.V.
    Inventors: Henri M. J. De Greve, Maria B. L. F. Salgado, Marc C. E. Van Montagu, Mark A. Vaeck, Marcus F. O. Zabeau, Jan J. A. Leemans, Hermanus F. P. Hofte
  • Bactericidal and/or bacteriostatic peptides isolated from hemolymph of honeybees
    Patent number: 5300629
    Abstract: New bactericidal and/or bacteriostatic, thermostable peptides which are isolated from hemolymph of immune honeybees and which are distinct from lysozymes, attacins, cecropins, diptericins and magainins. The peptides feature at least the 10 C-terminal amino acids of the following peptide:H.sub.2 N-Gly-Asn-Asn-Arg-Pro-X-Tyr-Ile-Pro-Gln-Pro-Arg-Pro-Pro-His-Pro-Arg-Z-OHin whichX is a valyl or isoleucyl residue andZ is a leucyl or isoleucyl residue.
    Type: Grant
