SensiFAST SYBR® Lo-ROX Kit has been developed for fast, highly reproducible real-time PCR and has been validated on commonly used real-time instruments.

A combination of the latest advances in buffer chemistry and enhancers, together with an antibody-mediated hot-start DNA polymerase system, ensures that the SensiFAST SYBR® Lo-ROX Kit produces fast, highly-specific and ultra-sensitive real-time PCR.

Features & Benefits

  • Rapid - hot-start capability saves time and reduces primer-dimer formation
  • Unique buffer chemistry - for highest specificity
  • Broad dynamic range - for high sensitivity
  • Simple and reproducible - just add primers and template

Instrument Compatibility

ABI 7500, 7500 FAST, ViiA7™, Stratagene (Agilent) Mx4000™, Mx3000P™, Mx3005P™ (See product selection table), as well as other instruments that do not require the use of a passive reference.


Description

SensiFAST SYBR® Lo-ROX Kit is designed for fast, highly sensitive and reproducible real-time PCR and has been validated on commonly used real-time instruments. The antibody-mediated hot-start DNA polymerase system reduces the chances of primer/dimers formation.

This allows a much greater dynamic range by removing competition for reaction components during amplification, in turn leading to greater sensitivity. The addition of the latest advances in buffer chemistry and enhancers also ensures that the SensiFAST SYBR® Lo-ROX Kit produces highly-specific and reproducible (fig. 1) real-time PCR results in under 30 minutes. For expression analysis, SensiFAST cDNA Synthesis Kit is the perfect partner for SensiFAST SYBR® Lo-ROX Kit for very fast cDNA synthesis and real-time results, without compromising sensitivity or quality.

For ease-of-use, SensiFAST SYBR® Lo-ROX is provided as a 2x mastermix containing all the components necessary for real-time PCR, including the SYBR® Green I dye, dNTPs, stabilizers and enhancers.

SensiFAST SYBR® Lo-ROX contains premixed ROX for optional use as a passive reference.

Frequently asked questions

  • What is the advantage of working with SYBR Green I?

      SYBR Green I is an inexpensive, universal dye which binds to all dsDNA. It can be easily used in combination with a simple primer pair to detect PCR products in real-time. This dye is very attractive for researchers analysing lots of different genes.

  • What is the advantage of working with a probe system?

      The probe system is always specific; only detect the gene of interest. It is also possible to distinguish between similar sequences with small differences like SNPs or mutations. In general, probe assays need less optimisation than SYBR Green I assays.

  • Can I use a SensiFAST Kit for standard real-time PCR?

      Although SensiFAST kits have been designed for fast PCR on the new generation of fast machines, they will work equally well for standard or fast PCR protocols on all real-time PCR machines.
  • Can I use a SensiFAST SYBR Kit for a probe assay?

      This is not possible because the SYBR is pre-mixed into the SensiFAST SYBR mastermix.
  • Why do the SensiFAST kits contain a hot-start Taq polymerase?

      Polymerase activity during the reaction set-up causes non-specific amplification including primer-dimer formation. To avoid non-specific amplification the polymerase is only activated after heating at 95°C for 2-3 minutes.
  • Why do you no longer sell kits contain dUTP (and UNG)?

      This is because it is because it is only effective if all the researchers either doing PCR in the laboratory or using the same thermocycler are also using a dUTP/dNTP and UNG system. If even one researcher is not, it ceases to be an effective control. Using dUTP has also been shown to be inefficient as it increases the Ct values by reducing reaction efficiency. Most labs do not need to use the dUTP method of control, optimised protocols will allow high specificity of PCR and good lab practices (using disposable consumables, the use of filter tips and maintaining a separate area for PCR set-up and PCR amplification and any post-PCR analysis) virtually eliminate the risk of cross contamination.
  • Why do certain kits contain a ROX passive reference?

      The emission recorded from ROX during the baseline cycles is used to normalize the emission recorded from the reporter (SYBR) in later cycles in some instruments. ROX compensates for small fluorescent fluctuations such as bubbles and well-to-well variations that may occur. Each of these instruments having the capacity to analyze the real-time PCR data with the passive reference signal either on or off.
  • Why are the ROX concentrations different?

      The amount of the ROX passive reference dye needed varies depending on the instrument optics, our SensiFAST kits have been optimised for these different instruments (see Product Selection Tool).
  • What is the difference between using ROX and using fluorescein?

      Fluorescein is an alternative passive reference dye used just in the Bio-Rad instruments (see Product Selection Tool), the SensiFAST SYBR & Fluorescein contains fluorescein premixed in the mastermix at optimised concentrations.
  • Is the SYBR in a separate tube?

      For your convenience the SensiFAST kits have an optimised amount of SYBR Green in the mastermix.
  • What is the difference between a one-step and a two-step real-time PCR reaction?

      In a one-step reaction the reverse transcription reaction and the real-time PCR reaction are done in one tube, making this a closed tube assay, so contamination can be avoided. It saves pipeting steps and time, and is easy in handling, making it ideal for high throughput screening.

      In a two-step reaction the reverse transcription reaction and the real-time PCR reaction are done in separate tubes. It gives a more flexible way of working in that the cDNA can be used for more than one real-time PCR reaction and can be archived, eliminating the need to continually isolate RNA. For convenience Bioline sells the SensiFAST cDNA Synthesis Kit separately if you wish to take a two-step approach.

Customer Testimonials

I had a very good experience with the SensiFAST SYBR Lo-ROX qPCR master mix. It was quick and easy to use, while also providing me with near perfect R-squared values and dissociation curves. Even when compared to other, more expensive, master mixes, I obtained results of equal or better quality.

"We applied the SensiFAST SYBR Lo-ROX Kit to investigate SFRP4 expression in primary and immortalized normal and cancer cell lines. We found that SensiFAST performed in a more sensitive way compared to two other real-time qPCR suppliers detecting SFRP4 expression one to two cycles earlier."
