Patents by Inventor Joseph Horwitz

Joseph Horwitz 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).

  • Chemically defined media compositions
    Patent number: 7598083
    Abstract: Chemically defined media compositions for the culture of eukaryotic cells are disclosed. The compositions are useful for eukaryotic cell culture in perfusion bioreactors and other vessels.
    Type: Grant
    Filed: October 27, 2005
    Date of Patent: October 6, 2009
    Assignee: Centocor, Inc.
    Inventors: David Epstein, Roger Monsell, Joseph Horwitz, Susan Lenk, Sadettin Ozturk, Christopher Marsh
  • Identification and characterization of reflectin proteins from squid reflective tissues
    Patent number: 7314735
    Abstract: A family of reflectin proteins is identified herein that is deposited in flat, structural platelets in reflective tissues of the squid Euprymna scolopes. These proteins are encoded by at least six genes in three subfamilies and have no reported homologues outside of squids. Reflectins possess 5 repeating domains, that are remarkably conserved among members of the family. The proteins have a highly unusual composition with four relatively rare residues (tyrosine, methionine, arginine, and tryptophan) comprising ˜57% of a reflectin, and several common residues (alanine, isoleucine, leucine, and lysine) occurring in none of the family members. These protein-based reflectors in squids provide a striking example of nanofabrication in animal systems.
