The Type-it Fast SNP Probe PCR Kit is intended for molecular biology applications. This product is not intended for the diagnosis, prevention, or treatment of a disease.

Product Details

The Type-it Fast SNP Probe PCR Kit is based on highly specific HotStarTaq Plus DNA Polymerase and a newly developed buffer system, both of which enable reliable and clear allelic discrimination. The combination of all components provided in the master mix result in improved accuracy and highly specific probe binding. The Type-it Fast SNP Probe PCR Kit is validated using TaqMan® SNP Genotyping Assays and enables reproducible SNP genotyping — even with difficult SNP loci (e.g., GC rich) or low amounts of starting template.


The Type-it Fast SNP Probe PCR Kit consistently ensures highly accurate SNP genotyping. 

Highly stringent and specific binding of the allele-specific probe 

The Type-it Fast SNP Genotyping PCR Master Mix is based on highly specific HotStarTaq Plus DNA Polymerase and a newly developed SNP genotyping PCR buffer system, both of which enable highly specific probe binding and consistently strong fluorescent signals. Compared to other commercially available SNP genotyping master mix chemistries, wider and clearer separation of allele clusters is obtained (see figure " Highly specific probe binding").

High call rates even for low template amounts

Even with challenging targets or difficult SNP loci, the Type-it Fast SNP Probe PCR Kit provides reliable SNP genotyping — well-separated allele clusters and tight clustering of identical alleles are achieved, resulting in high call rates  (see figure " Successful automated allele calling"). The Type-it Fast SNP Probe PCR Kit outperformed kits tested from other suppliers, ensuring tight clustering of alleles — even with 1 ng of template DNA (see figure " Reliable SNP genotyping with small amounts of template").

See figures


The Type-it Fast SNP Probe PCR Kit is available in a convenient master mix format consisting of highly specific HotStarTaq Plus Polymerase and a unique SNP genotyping buffer system designed for fast and efficient amplification. The unique kit components provide tight allele clustering and outstanding separation to ensure high call rates, enabling reproducible and accurate results (see table).

High specificity and sensitivity

HotStarTaq Plus DNA Polymerase, provided in the master mix, which ensures highly specific amplification, even with low template amounts. HotStarTaq Plus DNA Polymerase is provided in an inactive state with no polymerase activity at ambient temperatures. This prevents the formation of misprimed products and primer dimers at low temperatures. 

Unique buffer system

The Type-it Fast SNP PCR Buffer, also included in the master mix, is specifically designed for fast-cycling SNP genotyping using sequence specific 5'-nuclease probes. The unique composition of the Type-it Fast SNP PCR Buffer ensures highly stringent and specific binding of the allele-specific probe (match probe). This is due to the altered melting behaviour of the probes resulting in a narrower probe melting temperature window. Based on the original QIAGEN PCR Buffer, this innovative formulation enables a high ratio of specific-to-nonspecific primer binding during the short annealing step of every PCR cycle. Owing to a uniquely balanced combination of KCl and (NH4)2SO4, the PCR buffer provides stringent primer annealing conditions over a wider range of annealing temperatures and Mg2+ concentrations than conventional PCR buffers. Optimization of PCR by varying the annealing temperature or the Mg2+ concentration is dramatically reduced and often not required.

Additives in the Type-it Fast SNP PCR buffer, such as Q-Solution, provide reaction conditions for amplification of difficult genomic regions and difficult SNP loci. Innovative Q-Bond technology (for fast cycling) allows SNP genotyping results to be achieved faster (see figure " Mechanism of fast cycling during annealing"). The master mix also contains ROX dye at a concentration compatible with SNP genotyping on all instruments from Applied Biosystems. However, ROX dye is also compatible with other instruments not requiring ROX as a passive reference dye (see table).

The Type-it Fast SNP Probe PCR Kit is functionally verified with commercially available SNP genotyping assays and is compatible with TaqMan® MGB Probes, as well as user-developed probe-based assays consisting of TaqMan® MGB, TaqMan®, or other dual-labeled probes. The kit includes streamlined, preoptimized protocols for fast and reliable analysis.

Fast-cycling procedure for straightforward results

The Type-it Fast SNP Probe PCR Master Mix provides reaction conditions for fast-cycling PCR using sequence-specific probes. The buffer includes proprietary Q-Bond Molecule, which allows short cycling times on standard cyclers and on fast cyclers with rapid ramping rates. The fast-cycling procedure increases throughput by reducing PCR run times by up to 40% (see figure " Genotyping workflow"). 

Convenient kit format

The kit is provided in a ready-to-use, preoptimized master mix format for greater convenience. Use of a master mix saves time, simplifies handling for reaction setup, and increases reproducibility by eliminating many possible sources of pipetting errors and contamination —  pipetting steps are minimized and tedious calculations are eliminated. HotStarTaq Plus DNA Polymerase (included in the master mix) is activated by a 5-minute, 95°C incubation step, which can easily be incorporated into existing thermal cycling programs. Room-temperature reaction setup using the master mix is fast and easy.

Suitable instruments

The Type-it Fast SNP Probe PCR Kit is optimized for amplification of SNP PCR assays on any suitable standard and fast ramping cycler compatible with optical PCR plates that fit into real-time PCR instruments used for fluorescence plate read analysis (see table).
