  • Expression and purification of ATM protein using vaccinia virus
    Patent number: 6994975
    Abstract: The present disclosure concerns methods for recombinantly producing functional ataxia-telangiectasia (ATM) protein, methods for isolating recombinant functional ATM protein, and uses of ATM protein. In particular, a method is disclosed for using a vaccinia virus vector to express ATM, and using immunoprecipitation or affinity tagging to isolate recombinant ATM.
    Type: Grant
    Filed: January 8, 2002
    Date of Patent: February 7, 2006
    Assignee: The Regents of the University of California

  • Method of analyzing ataxia-telangiectasia protein
    Publication number: 20040029198
    Abstract: The present disclosure concerns methods for recombinantly producing functional ataxia-telangiectasia (ATM) protein, methods for isolating recombinant functional ATM protein, and uses of ATM protein including diagnosing a patient for A-T and/or susceptibility to various conditions including cancer, particularly breast cancer, neurological disorders, and heart disease. Specifically, a method is disclosed for determining the amount of ATM protein in a patient's cells, comparing that amount to a reference, and forming a diagnosis.
