PCR Highly Functional PCR Enzyme

Tth DNA polymerase is a family A DNA polymerase derived from the thermophilic bacteria Thermus thermophilus (Tth) HB8 (1). This polymerase exhibits reverse transcriptase activity in addition to DNA polymerase activity in the presence of Mn2+ions. Therefore, this enzyme enables "one-step RT-PCR" including reverse transcription and PCR steps. Moreover, this enzyme exhibits 5'→3' exonuclease activity that can be used in the TaqMan® assay in real-time PCR.
