Beschreibung
Zusammenfassung:	The present invention provides methods, compositions, and kits for storing and enhancing the activity of polymerases and particularly thermostable polymerases. The methods comprise mixing a thermostable polymerase with at least one zwitterionic or ylide surfactant that has at least one PEO group. In another aspect the polymerase is mixed with a blocker such as PLURONIC® or TETRONIC® or an amine N-oxide derivative thereof. The thermostable polymerase may be reversibly inactivated by treatment with 2-(Methylsulfonyl)ethyl 4-nitrophenyl carbonate. Compositions and kits for performing the process according to the invention are also provided.
