  • Compositions of alpha platelet derived growth factor receptor nucleic acid and protein and method of making
    Patent number: 7427671
    Abstract: A DNA sequence which encodes a human type ? platelet derived growth factor receptor protein which preferentially binds to the AA homodimer and AB heterodimer forms of platelet derived growth factor and also binds the BB homodimer at high affinity, is described. Substantially pure human a platelet derived growth factor receptor protein and methods for recombinantly producing human ? platelet derived growth factor receptor protein are also described.
    Type: Grant
    Filed: May 11, 1995
    Date of Patent: September 23, 2008
    Assignee: The United States of America as represented by the Secretary, Department of Health and Human Services
    Inventors: Toshimitsu Matsui, Stuart A. Aaronson, Jacalyn H. Pierce
  • Methods for identifying alpha PDGFR agonists and antagonists
    Patent number: 7252929
    Abstract: Discoveries are disclosed that show particular aspects of recombinant DNA technology can be used successfully to produce a hitherto unknown type of human Platelet-Derived Growth Factor (PDGF) receptor protein free of other PDGF receptors. These proteins can be produced from DNA segments in cells in various functional forms. These forms variously enable biochemical and functional studies of these novel receptors as well as production of antibodies. Means are described for determining the level of expression of genes for specific types of PDGF receptor proteins, for example, by measuring mRNA in cells with PDGF receptor type-specific DNA probes or by measuring antigen in biological samples with type-specific antibodies.

  • Immunoassays for the alpha platelet-derived growth factor receptor
    Patent number: 6228600
    Abstract: Recombinant DNA technology was used to clone encoding nucleic acids for the human alpha platelet-derived growth factor receptor (PDGF-R type alpha). Peptides corresponding to the predicted sequence of this type and of the PDGF-R type beta were used to elicit antibodies specific for either type of the PDGF-R. Immunoassays are described for determining the level of PDGF-R type alpha in biological samples with the PDGF-R type alpha-specific antibodies.
