  • Producing telomerase activators and inhibitors by screening with purified telomerase
    Patent number: 7067283
    Abstract: This invention provides purified telomerase and methods of purifying it. The methods involve the use of several sequential steps, including the use of matrices that bind molecules bearing negative charges, matrices that bind molecules bearing positive charges, intermediate-selectivity matrices, methods that separate molecules based on their size, shape, or buoyant density, and by affinity purification.
    Type: Grant
    Filed: March 26, 2004
    Date of Patent: June 27, 2006
    Assignee: Geron Corporation
    Inventors: Scott L. Weinrich, Edward M. Atkinson, III, Serge P. Lichtsteiner, Alain P. Vasserot, Ronald A. Pruzan
  • Using purified telomerase to identify telomerase activators and inhibitors

  • Purified telomerose
    Patent number: 6261556
    Abstract: This invention provides purified human telomerase and methods of purifying it. The methods involve the use of several sequential steps, including the use of a first matrix that binds molecules bearing negative charges, a matrix that binds molecules bearing positive charges, a second matrix that binds molecules bearing negative charges, an affinity purification step and a matrix that separates molecules according to their size.
