BioMaster RT-qPCR SYBR Blue (2×)

  • Gene expression analysis;
  • One-step real-time RT-PCR.

Basic description

BioMaster RT-PCR SYBR Blue (2×) reagent kit includes 2× buffer for RT-PCR with SYBR containing all the necessary components (except for DNA template and primers), intercalating dye SYBR Green I, BioMaster-mix and DEPC-treated water. The kit is designed for one-step reverse transcription and real-time polymerase chain reaction (qRT-PCR).

BioMaster-mix contains the optimal ratio of M-MuLV –RH to HS-Taq DNA polymerase for both reactions.

M-MuLV –RH is a genetically modified Moloney Murine Leukemia Virus reverse transcriptase (M-MuLV). The enzyme exerts RNA- and DNA-dependent polymerase activity but lacks RNase H activity. M-MuLV –RH reverse transcriptase exhibits improved thermal stability and is active at high temperatures (up to 50°С).

HS-Taq DNA polymerase is a recombinant Taq DNA polymerase inactivated by specific monoclonal antibodies. The enzyme is inactive at temperatures up to 70 °C, it is activated at the first PCR cycle during a short 5-min incubation at 95 °C. Recombinant HS-Taq DNA polymerase catalyzes 5’→3’ synthesis of DNA and possesses 5’→3’ exonuclease activity of the native Taq DNA polymerase from Thermus aquaticus. Recombinant HS-Taq DNA polymerase is ideal for conventional PCR of the templates of up to 5 kbp.

2× buffer for RT-PCR with SYBR is optimized for both efficient RT and real-time PCR. It contains additives and enhancers that enable efficient RT-PCR of complicated and GC-rich templates. Blue hue of the reaction solution provided by the inert dye allows control when using multi-well plates.

SYBR Green I
SYBR Green I is a fluorescent intercalating dye for quantitative and qualitative detection of PCR products during real-time PCR. SYBR Green I provides easy and economical way for detection and quantitative assessment of PCR products during real-time PCR without a need of using specific fluorescent probes. During amplification, SYBR Green I dye penetrates into the minor groove of DNA products and emits stronger fluorescent signal than the unbound dye. Absorption and emission maxima of SYBR Green I are 494 nm and 521 nm, respectively, which enables its usage with any real-time PCR platform existing to date.
Inert dye
The inert dye included in 2× buffer for RT-PCR with SYBR does not reduce PCR efficiency; it facilitates monitoring of multi-well plate pipetting. Absorption maximum of the blue dye is 615 nm.

Limits of use
The presence of the fluorescent dye renders usage of fluorescent probes.

Areas of use

  • Gene Expression Analysis
  • RT-PCR one- and two-step

Reaction mixture properties

  • The reaction mix is optimized for the specific and effective performance of M-MuLV –RH reverse transcriptase and HS-Taq DNA polymerase;
  • The mix contains substances that allow long-term storage (storage of BioMaster RT-PCR SYBR Blue (2×) at room temperature for 2 days and/or multiple thawing-freezing cycles do not affect RT-PCR efficacy);
  • The mix contains fluorescent dye SYBR Green I, which allows real-time monitoring of PCR.

Benefits of using

  • The mix is colored for easy pipetting
  • High specificity
  • High sensitivity (1pg – 1 µg of RNA)
  • Easy and convenient in use
  • Low pipetting error and low risk of cross-contamination
  • Standardized conditions of the same-type reactions (reduced pipetting error during mixing PCR components in a series of experiments)


9 months (under proper storage and transportation conditions).


at -20 °С; not more than 30 thawing-freezing cycles.
