  • Method for enhancement of sperm survival using soluble peripheral protein fraction of APM
    Patent number: 7070918
    Abstract: A method of improving and/or prolonging sperm viability which comprises contacting spermatozoa with an isolated, cell-free protein fraction of oviductal apical plasma membrane (APM). This finds use in maintenance of sperm viability to increase the success rate of artificial insemination (AI).
    Type: Grant
    Filed: October 31, 2002
    Date of Patent: July 4, 2006
    Inventors: William Vincent Holt, Alireza Fazeli, Paul Frederick Watson

  • Factors for enhancement of sperm survival
    Publication number: 20040086842
    Abstract: A method of improving and/or prolonging sperm viability which comprises contacting spermatozoa with an isolated, cell-free, protein obtainable from a peripheral membrane fraction of oviductal apical plasma membrane (APM), or a fragment or derivative therefrom, the protein having a molecular weight of between approximately 10 kDa and 100 kDa, which finds use in maintenance of sperm viability to increase the success rate of artificial insemination (AI).
