Penelope E Roberts 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).

  • Publication number: 20040146990
    Abstract: The present invention provides a method for generating a population of monoclonal antibodies capable of binding to antigens representative of a particular cell type. The method is unique in that it minimizes the generation of non-representative antibodies cross-reacting with proteins not present in a particular cell type; it also maximizes the preservation of intact antigens, especially surface antigens, for production of a plurality of monoclonal antibodies that bind to the native antigens. The present invention also includes a method of determining the combination of cell surface antigens present on a specific cell type. Further provided by the invention are hybridomas, populations of monoclonal antibodies produced by the hybridomas of the present invention.

  • Publication number: 20040037833
    Abstract: The invention provides the identification and characterization of disease and cancer-associated antigen, RAAG10. The invention also provides a family of monoclonal antibodies that bind to antigen RAAG10, methods of diagnosing and treating various human cancers and diseases that express RAAG10.

  • Publication number: 20020192816
    Abstract: The invention discloses a substantially pure population of human pancreatic progenitor cells and methods of isolating and culturing the pancreatic progenitor cells. By carefully manipulating the microenvironment of the pancreatic progenitor cells, multiple passages are attainable wherein the pancreatic progenitor cells do not senesce and furthermore, are capable of becoming functional exocrine or endocrine cells. In addition, several methods of use of human pancreatic progenitor cells are disclosed herein.

  • Patent number: 5830685
    Abstract: A novel bronchial or bronchiolar epithelial cell from normal neonatal mammalian lung has been isolated, established and maintained for multiple passages in the absence of serum, without undergoing crisis or senescence. By careful manipulation of the nutritional/hormonal microenvironment we have been able to select, from a heterogeneous population, a single epithelial cell type which can maintain highly differentiated features in vitro. This cell type has characteristics of bronchiolar epithelial cells. A clonal line, RL-65, has been selected and observed for more than 3 years in continuous culture. It has been characterized by ultrastructural, morphological and biochemical criteria.

  • Patent number: 5364785
    Abstract: A novel bronchial or bronchiolar epithelial cell from normal neonatal rat lung has been isolated, established and maintained for multiple passages in the absence of serum, without undergoing crisis or senescence. By careful manipulation of the nutritional/hormonal microenvironment we have been able to select, from a heterogeneous population, a single epithelial cell type which can maintain highly differentiated features in vitro. This cell type has characteristics of bronchiolar epithelial cells. A clonal line, RL-65, has been selected and observed for more than 2 years in continuous culture.
