|Source||Isolated from E.coli strain that carries the cloned T4 DNA polymerase gene|
|Description||T4 DNA Polymerase catalyzes the synthesis of DNA in the 5` -> 3` direction and requires the presence of template and primer. This enzyme has a 3` -> 5` exonuclease activity.|
- polishing ends;
- probe labeling using replacement synthesis.
