  • Peptide analogs of insulin-like growth factor II
    Patent number: 5470828
    Abstract: The invention provides peptide analogues of insulin-like growth factor-1 (IGF-1) or factor-2 (IGF-2). The peptide analogues of IGF-1 have at least the glutamic acid residue at position 3 replaced by another amino acid. The peptide analogues of IGF-2 are replaced at position 5 or 6 with another amino acid.
    Type: Grant
    Filed: September 17, 1992
    Date of Patent: November 28, 1995
    Assignee: Gropep Pty. Ltd.
    Inventors: Francis J. Ballard, John C. Wallace, Julian R. E. Wells
  • Peptide analogues of insulin-like growth factor 1 (IGF-1) or factor 2 (IGF-2)
    Patent number: 5164370
    Abstract: Peptide analogues of insulin-like growth factor 1 and growth factor 2 are disclosed. When the analogue is an analogue of growth factor 1 the glutamic acid residue is absent from position 3 of the N-terminal and either the glutamic acid residue or the threonine residue adjacent to glutamic acid residue at position 3 is replaced by a different amino acid residue. When the peptide analogue is an analogue of insulin growth factor 2 the glutamic acid residue position 5 is absent. Preferred peptide analogues are disclosed. Methods of use in pharmaceutical and veterinary preparations are described.

    Patent number: 5077276
    Abstract: A peptide analogue of mammalian insulin-like growth factor-1 wherein from 1 to 5 amino acid residues are absent from the N-terminal.
    Type: Grant
    Filed: February 12, 1990
    Date of Patent: December 31, 1991
    Assignee: Gropep Pty Ltd
    Inventors: Francis J. Ballard, John C. Wallace, Geoffrey L. Francis, Christopher J. Bagley
  • Modified zein genes containing lysine
    Patent number: 4886878
    Abstract: Modified 19kd and 22kd zeins containing lysine are provided. Lysine additions are made by modifying structural genes which encode 19kd and 22kd pre-zeins. Modified zeins produced from the modified structural gene templates are found to retain important properties of unmodified zeins, having similar molecular weights, having the ability to form protein bodies within the rough endoplasmic reticulum of a host cell and being soluble in alcohol.
