  • Compositions comprising polynucleotides encoding human fibroblast growth factor receptor and uses thereof
    Patent number: 6844168
    Abstract: A new receptor for fibroblast growth factor has been cloned and expressed. The recombinant receptor is useful for inhibiting FGF activity, and for screening compounds for binding activity similar to that of FGF. A soluble, truncated recombinant receptor is also prepared, and is capable of binding FGF.
    Type: Grant
