Shane Crawford Weber 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).

  • Collagen-like polypeptides and biopolymers and nucleic acids encoding same
    Patent number: 5801045
    Abstract: Synthetic biopolymers can be prepared using recombinant DNA technology or chemical synthetic methods which have properties similar to naturally occuring gelatin or collagen. These materials comprises one or more polypeptides having the peptide sequence represented by the formulae: ##STR1## whereinXaa.sub.1 and Xaa.sub.2 are independently the amino acids identified as Met, Ile, His, Lys, Asn, Tyr or Gln, and n is 1 to 25.
    Type: Grant
    Filed: March 10, 1997
    Date of Patent: September 1, 1998
    Assignee: Eastman Kodak Company
    Inventors: Shane Crawford Weber, John Alan McElver
  • Method for recombinant yeast expression and isolation of water-soluble collagen-type polypeptides
    Patent number: 5710252
    Abstract: A method for preparing and purifying collagen-type polypeptides (or biopolymers) has been developed. The polypeptides are prepared by recombinant DNA technology using yeast host cells. Once expressed in the host cell culture, the polypeptide is purified by a series of centrifugations, isoprecipitation, ion exchange (or other chromatography), and diafiltration steps. Treatments with a protease and a calcium salt are also carried out at some point. It is also desirable to diafilter the purified fractions from the last chromatography to exchange ions which make the resulting polypeptide more compatible with its intended use.
