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.
