  • Isolated polynucleotide sequences encoding a fertility associated antigen
    Patent number: 6891029
    Abstract: The present invention provides an isolated polynucleotide sequence and amino acid sequence for a bovine fertility associated antigen (FAA), methods of producing recombinant bovine FAA protein; methods of increasing the stability of the plasma membrane, acrosome, and/or other portions of a sperm cell by mixing with FAA and/or recombinant FAA protein(s); and increasing fertility of bulls by mixing sperm cells with FAA and/or recombinant FAA protein(s).
    Type: Grant
    Filed: July 16, 2001
    Date of Patent: May 10, 2005
    Assignee: The Arizona Board of Regents on behalf of the University of Arizona
    Inventors: Huanmin Zhang, Roy L. Ax, Mary E. Bellin

  • Monoclonal antibody detection of proteins on sperm related to fertility
    Patent number: 5962241
    Abstract: Heparin binding proteins (HBP) are produced by male accessory glands and bind to sperm at ejaculation. The ability of accessory glands to produce HBP and sperm to bind HBP differs among males. Identifying the presence of a 21.5, 24 and 30 kDa heparin binding proteins in sperm membranes with a monoclonal antibody resulted in separating groups of bulls by 40% difference in fertility. Thus, fertility potential of a bull can be predicted by heparin binding protein content of sperm membranes.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: October 5, 1999
    Assignee: The University of Arizona
    Inventors: Roy L. Ax, Mary E. Bellin
  • Ova fertilization assay
    Patent number: 4772554
    Abstract: A method for assaying the fertilization potential of a mammalian ovum that has been removed from an ovarian follicle, together with a portion of accompanying follicular fluid. The method includes the step of measuring the concentration of at least one selected glycosaminoglycan in the follicular fluid accompanying the ovum to be tested. That concentration is then compared with concentrations of the same glycosaminoglycan characteristic of the follicular fluid of atretic and non-atretic follicles.
