Patents by Inventor Marketta Hormia

Marketta Hormia 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).

  • Promotion of epithelial cell adhesion and hemidesmosome assembly by a laminin-like molecule
    Patent number: 5658789
    Abstract: A method for growing epithelial cells in vitro using soluble proteins secreted by 804G and NBT-II rat bladder carcinoma cells. These proteins stimulate cell attachment and hemidesmosome formation in cells grown in contact with the proteins. The protein is purified from conditioned medium by immunoaffinity chromatography using a monoclonal antibody generated against the protein. The purification of these proteins may be facilitated by culturing the cells under low serum or serum free conditions.
    Type: Grant
    Filed: May 19, 1995
    Date of Patent: August 19, 1997
    Assignee: Desmos, Inc.
    Inventors: Vito Quaranta, Marketta Hormia
  • Soluble factor stimulation of attachment and hemidesmosome assembly in epithelial cells
    Patent number: 5422264
    Abstract: A method for growing epithelial cells in vitro using soluble proteins secreted by 804G rat bladder carcinoma cells. These proteins are able to stimulate cell attachment and hemidesmosome formation in cells grown in contact with the proteins. The purification of these proteins from 804G culture supernatant is greatly facilitated by culturing the cells under low serum conditions.
