The qScriber™ cDNA Synthesis Kit is a highly efficient and simple-to-use system for cDNA synthesis eliminating the need for tedious reaction optimization. The qScriber™ Enzyme Blend ensures high sensitivity detection from low copy number targets. The highly active and thermostable HighScriber™ Reverse Transcriptase blended with RNase Inhibitor allows for an efficient cDNA synthesis and reaction safety. The wide reaction temperature range (38°C - 55°C) ensures efficient transcription from GC rich templates.

The 5X qScriber™ Reaction Mix includes optimal concentrations of magnesium and dNTPs and a combination of anchored oligo (dT) and random hexamers for unbiased representation of mRNA ends.

The kit is an optimal choice for generating high quality cDNA from viral RNA, miRNA or other targets for qPCR or for PCR.

For the maximum convenience the Kit includes even the PCR Water to set up the reaction, so the only thing you need to take care of is the high quality RNA template.

Important Notes
  • RNA is sensitive to degradation by RNases present everywhere. Take care to protect RNA from degradation keep your bench clean, wear gloves, use sterile tubes and filter pipet tips.
  • Include positive and negative controls in parallel.
  • Thaw and keep reagents on ice. Mix well before use.
  • Do not add any other components into the reaction with exception of the template and the supplied reagents.
  • The recommended reaction temperature is 42-50°C. For GC rich templates, the temperature can be increased up to 55°C.
Prepare a 20 µl reaction:
5X qScriber™ Reaction Mix 4 µl
qScriber™ Enzyme Blend, 20X 1 µl
Total RNA
1 pg to 5 µg
PCR Water up to 20 µl


  • Mix gently, avoid bubbles.
  • Incubate 30 min at 42-50°C to synthesize cDNA.
  • Inactivate the enzyme at 85°C for 10 min.
  • Store reactions at -20°C or on ice for an immediate use.
  • Use 2-4 µl of this reaction mix per 20 µl qPCR reaction.
