  • Serum markers associated with early and other stages of breast cancer
    Patent number: 9140704
    Abstract: Methods for identifying disease-specific markers, in particular breast cancer markers, by electrophoretically separating serum albumin complexes in a biological sample on a membrane are provided. Electrophoretic separation profiles representing different diseases or different cancer stages can be produced, and used in the diagnosis, prognosis and treatment of these diseases. Methods for identification of a cancer peptide fragment comprising a cancer peptide motif are provided. Also provided are breast cancer and other cancer markers and antibodies that specifically recognize these markers.
    Type: Grant
    Filed: July 13, 2010
    Date of Patent: September 22, 2015
    Assignee: Temple University of The Commonwealth System of Higher Education
    Inventors: Frank N. Chang, Phu T. Duong, George P. Tuszynski
  • Method for detecting disease markers
    Patent number: 8333880
    Abstract: Disease specific markers, in particular cancer markers, can be detected by electrophoretically separating proteins and protein complexes from a biological sample on a protein binding polymeric membrane in a low conductivity, water-miscible organic solvent buffer. Electrophoretic separation profiles representing different diseases can be produced, and used in the diagnosis or prognosis of these diseases.

  • Method for detecting cockroach allergens and determining total allergen level
    Patent number: 7033777
    Abstract: The present invention is directed to a method and a test kit for detecting cockroach allergens and/or determining the total allergen level. A sample from an environment in which cockroaches are present or are suspected to be present is provided. The sample and a substrate composition comprising a chitinase substrate are then contacted. The presence of cockroach allergens can be determined by observing or detecting the magnitude of a measurable change of a property of the substrate composition following the contact between the sample and the substrate composition wherein the magnitude of the measurable change of a property of the substrate composition is proportional to the total allergen level. The total allergen level can be determined by measuring the magnitude of the measurable change of a property of the substrate composition, or by comparing the magnitude with a reference standard.
