  • Amplify directly from RNA. Benefit from the intrinsic reverse transcriptase activity of Tth Polymerase to directly amplify from RNA in one step.
  • Improve PCR yield. Obtain more PCR product, because the Tth Polymerase is stable during prolonged repetitive high temperature incubations.
  • Enhance specificity of amplification. Avoid loss of specificity due to RNA secondary structure using the higher annealing temperature Tth Polymerase allows compared to other reverse transcriptases.
