Product Introduction
In the presence of templates and primers, T4 DNA Polymerase catalyzes DNA synthesis in the 5 →3 direction. This enzyme also has the activity of 3 →5 exonuclease which is stronger than E. coli DNA polymerase I. Unlike DNA polymerase I, T4 DNA Polymerase does not have 5 →3 exonuclease activity.
Application
1. Removal of 3’ overhangs to form blunt ends;
2. Fill-in of 5’ overhangs to form blunt ends;
3. Labeling DNA probe synthesis through displacement reaction;
4. Synthesis of the second strand during site-directed mutagenesis;
5. PCR product cloning without relying on ligation reactions.
