SourceIsolated from E.coli strain that carries the cloned T4 DNA polymerase gene
DescriptionT4 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.
