Thermus thermophilus 111


  • Suitable for high temperature synthesis of DNA (1)
  • Tth III Reverse Transcriptase synthesizes cDNA from RNA template (2)
  • Results in greater specificity of primer hybridization and extension of RNA
  • Can reverse transcribe at elevated temperatures (2)
  • Minimizes problems with strong secondary structure of RNA
  • Used for efficient PCR of DNA, containing problematic secondary structures
  • Applicable to RT-PCR; the same enzyme is used for both reverse transcription and following amplification of obtained cDNA template (2)
  • Resistant to amplification inhibitors present in template DNA isolated from problematic samples (3,4)
