  • Patent number: 5688763
    Abstract: Growth hormone receptor and growth hormone binding protein are purified enabling amino acid sequence and DNA isolates coding for growth hormone receptor and growth hormone binding protein and methods of obtaining such DNA are provided, together with expression systems for recombinant production of growth hormone receptor and growth hormone binding protein. Therapeutically useful forms of the growth hormone receptor and growth hormone binding protein and anti-receptor antibodies are described.
    Type: Grant

  • Patent number: 4857637
    Abstract: The activity of growth-associated receptors is modulated in vivo in a controlled and reproducible fashion by immunizing animals against target growth-associated receptors. This is accomplished by the use of immunogens predetermined to induce primarily agonist or antagonist responses. The immunogens include anti-ligand antibodies and receptor derivatives.
