Overview
Transcriptor Reverse Transcriptase is the robust recombinant reverse transcriptase with thermostability up to +60°C, for transcription of RNA fragments up to 14 kb in two-step RT-PCR applications.
+-
Application
Use Transcriptor Reverse Transcriptase for synthesis of cDNA from total RNA or mRNA for:
  • Two-step RT-PCR applications using conventional thermal cyclers or real-time PCR instruments
  • RT-PCR for detection of viral RNA
  • TMA and NASBA nucleic acid amplification methods
  • Synthesis of full-length cDNA up to 14 kb for libraries or cloning
  • Rapid amplification of cDNA end (RACE)
+-
Specification
Transcriptor Reverse Transcriptase offers higher thermostability compared to the native forms of AMV or M-MLV reverse transcriptase, allowing higher temperatures for reverse transcription, achieving high performance with GC-rich RNA fragments and difficult secondary structures.
Enzyme activities: RNA-dependent DNA polymerase, DNA-dependent DNA polymerase, unwinding activity, RNase H (degrading RNA in RNA:DNA hybrids)
Recommended reaction temperature: +42 to +65°C
Substrates: Incorporates dNTP, ddNTP, dUPT, various labeled or modified nucleotides
Divalent ion requirement: Mg2+
Appearance: Clear, colorless solution
Storage buffer: Potassium phosphate, 200 mmol/L; DTT, 2 mmol/L; Triton X-100, 0.2% (v/v); glycerol, 50% (v/v), pH approximately 7.2
Volume activity: ≥20 U/μL
Specific activity: ≥50 kU/mg protein
Unit definition: One unit Transcriptor Reverse Transcriptase is defined as the amount of enzyme which incorporates 1 nmol of [3H]TMP into an acid insoluble product in 10 minutes at +37°C with poly(A)x(dT)15 as substrate.
