Volcano3G RT-PCR 2× Master Mix

Cat. No. 6101
Size 100 tests / 500 tests
Store -20°C


Volcano3G RT-PCR Probe 2x Master Mix contains all components necessary for a successful and reliable real-time RT-qPCR in all standard PCR cyclers, including dNTPs and an optimized reaction buffer. An aptamer-based hot-start formulation of the Volcano3G DNA polymerase prevents false amplification. Temperatures above 50°C cause the aptamer's secondary structure to melt and will set-free the polymerase
  • Rapid detection and identification of  RNA & DNA targets
  • Reverse transcription qPCRs (RT-qPCRs)
  • qPCRs
Experimental recommendations for first use
  • Run a PCR with a temperature gradient at the annealing / extension step in order to find the optimal temperature for your assay.
  • Most RT-PCR assays work well with a short 80°C (1 min) denaturation step and a reverse transcription step at 50-55°C (10 min) followed by standard PCR cycling conditions.

Typical RT-PCR protocol

Initial denaturation step


60 sec

Reverse Transcription step*


600 sec



50 sec



10 sec (35-50 cycles)






A two-step as well as three-step PCR protocols can be used.
* Volcano3G DNA polymerase allows “zero-step” RT-PCRs directly from RNA templates (without an isothermal reverse transcription step), as reverse transcription also takes place simultaneously with DNA amplification during the cycled PCR elongation step. Thus a reverse transcription step is optional and can be omitted in some cases.
** A new RT-PCR is ideally established by running a temperature gradient in order to find the best reverse transcription / annealing / extension temperature for each primer pair. The annealing temperature of a primer is strongly influenced by its nucleic acid sequence and the reaction buffer composition (salts and pH). Volcano3G DNA polymerase is fully thermostable and most active between 55-95°C.
Quality Control Assays RT-PCR activity
Volcano3G RT-PCR Probe Mix is tested for a successful RT-qPCR performance. A 151 bp fragment (HPRT1 mRNA) is amplified from human total RNA extract and the linearity of amplification over a specified serial dilution is demonstrated. DNA polymerase activity: Volcano3G DNA polymerase activity is monitored and adjusted to a specific DNA polymerase activity using an artificial DNA template and DNA primer. Enzyme concentration is determined by protein-specific staining. Please inquire more information at info@mypols.de for the lot-specific concentration. No contamination has been detected in standard test reactions.

Important notes
  • Volcano3G RT-PCR Probe 2x Master Mix works very well also for DNA amplification assays
  • This master mix is optimized for an amplicon size between 60- 300 bp.
  • Minimize the number of freeze-thaw cycles by storing in aliquots. For a day-to-day use, we recommend keeping an aliquot at 4°C.
