Stan Blecher 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).

  • Sex-chromosome-specific proteins, species specific and sperm specific proteins and methods for their identification and isolation
    Publication number: 20030162238
    Abstract: Sex-chromosome-specific molecules associated with animal sperm cell membranes, and the method for isolating them, are described. An X chromosome specific molecule, a protein, having an apparent molecular weight of 32 kDa on SDS-PAGE is specifically described. The method involves preparing a cell membrane fraction from animal sperm cells; treating the cell membrane fraction with one or more substances which bind to X or Y chromosome specific molecules in the cell membrane fraction to form conjugates between the X or Y chromosome specific molecules and the substances; separating the material in the cell membrane fraction which does not bind to the substances to obtain a subfraction containing sex-chromosome-specific molecules. Methods of using the sex-chromosome-specific molecules for sperm sexing are also described.
