T4 DNA Polymerase

Contact us


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

- 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

Purified from a strain of E. coli that expresses the recombinant T4 DNA Polymerase gene.
