商品信息

T4 DNA Polymerase catalyzes the extension of a primed DNA template in the 5′→ 3′ direction. This enzyme exhibits a powerful 3′→ 5′ exonuclease activity; it lacks any inherent 5′→ 3′ exonuclease or strand displacement functions.




Description:
T4 DNA Polymerase catalyzes the extension of a primed DNA template in the 5' -> 3' direction. This enzyme exhibits a powerful 3' -> 5' exonuclease activity, while lacking any inherent 5' -> 3' exonuclease or strand displacement functions.
Specific Activity:
5,555U/mg
Application:
- 3'-overhang removal to form blunt ends
- 5'-overhang fill-in to form blunt ends
- Single strand deletion for sub-cloning
- Second strand synthesis in site-directed mutagenesis
- Probe labeling using replacement synthesis
