Customer Q&As

What are the advantages of the Tth DNA Polymerase?

A: The Tth DNA Polymerase has high purity (SDS-PAGE ≥ 95%); no exonuclease, DNase, RNase residues; high heat stability up to 95°C; and a PCR amplification detection sensitivity of up to 100 pg.

Can it be used to amplify complex templates?

A: In the presence of Mn2+, the enzyme exhibits strong reverse transcriptase activity at 55-70°C, is compatible with complex templates, and has no RNase H activity, showing excellent performance in one-step RT-PCR reactions.

What is the enzymatic activity?

A: Tth DNA polymerase is a heat-resistant DNA polymerase discovered from Thermus thermophilus HB8 and has 5′-3′ DNA polymerase activity and 5′-3′ exonuclease activity in the presence of Mg2+, with no 3′-5′ exonuclease activity. It can be widely used in PCR amplification reactions.
