Methods and compositions for enriching compositions for polymerase enzyme complexes

Abstract:

The present invention provides methods, compositions, and systems for enriching compositions for polymerase enzyme complexes. In particular, the methods, compositions, and systems of the present invention remove free polymerases from the compositions using one or more purification steps, including protease treatment, thus enriching the compositions for polymerases complexed with a template nucleic acid.
