Testing for pathogenic E. coli like EHEC, EPEC , EIEC etc. can help to prevent foodborne infections as it has taken place in 2011 with E. coli strain O104 in Germany and with strain O157 at other places in the world. The real-time PCR kit allows the detection of stx1, stx2 and the eaeA gene which covers all different strains of pathogenic E. coli. It also includes a test for Shigella. The test can also be used for the confirmation of bacterial colonies.

Taq DNA Polymerase is a highly thermostable recombinant DNA polymerase derived from the thermophile Thermus aquaticus. The molecular weight of the recombinant protein is 94 kD. The Taq Polymerase is able to amplify DNA up to 5 kb with an elongation velocity of 0,9 to 1,2 kb/min at 70 to 75 °C. The error rate of this Taq Polymerase is ~2,2×10⁻⁵ nucleotide⁻¹ cycle⁻¹. Taq DNA polymerase catalyses the 5’→3’ synthesis of DNA. The enzyme has no detectable 3’→5’ proofreading exonuclease activity, and possesses low 5’→3’ exonuclease activity, which results in a 3’-dA overhang on the PCR product

OneCup it‘s so easy! The OneCup assay comes along with a minimum of pipetting steps. Everything is included in the mix. You only need to combine 20 μl of the mix with 2 μl of your DNA sample and everything is ready. You have a minimum of hands-on time and avoid mistakes during pipetting. You can run the test on all common block cyclers. Application: Detection of Salmonella in food samples and environmental samples subsequent to a pre-enrichment step according to DIN EN ISO 20837 and 20838. In combination with an appropriate pre-enrichment and DNA preparation the test complies with the official method of the German food and feed law §64. ASU L00.00-98. Test principle: The test is dedicated to detect DNA of Salmonella in a sample using Real-Time PCR in compliance with the ISO method mentioned below. The kit uses the TaqMan® principle. Thus the requirements of the ISO standard, that an amplification product has to be confirmed by a hybridization step, is fulfilled. Each reactions contains an internal amplification control. Therefore, false negative results due to inhibition of the reaction can be excluded. The test included the UNG enzyme to prevent re-amplification of contaminating amplicons.

The NovaTaq PCR Master Mix is a ready to use 2X concentrated mixture of NovaTaq DNA polymerase, ultra-pure deoxynucleotides, and reaction buffer without magnesium chloride. The master mix simplifies the assembly of PCR reactions and offers advantages of times savings, consistency, and minimal risk of contamination. Simply add the NovaTaq PCR master mix to an equal volume containing the required amount of magnesium chloride, DNA template, and primers, and the reaction is ready for thermal cycling. The final diluted reaction contains 2,5 units of NovaTaq DNA polymerase per 100 µl. Sufficient components are included for 200 standard 50 µl (or 100×100 µl) amplification reactions.

This SuperMix is a 2X concentrated, ready to use reaction cocktail for Real-Time qPCR that contains all components, except primers, probes, and templates. The system transcends multiplex limitations of conventional PCR master mixes, enabling unbiased amplification of up to five target sequences in a single tube. Suppression of low copy amplicons by high copy reference targets in the amplification is a common problem in multiplex PCR. This can skew, or mask the apparent representation and quantification of low copy target sequences. PerfeCTa® MultiPlex qPCR SuperMix delivers dynamic range and sensitivity to multiplexed qPCR that is comparable to that for singleplex qPCR probe assays without the need for limiting or variable primer concentrations.

Synthesis of cDNA and PCR amplification are carried out in the same tube without opening between procedures. These kits are optimised to deliver maximum RT-PCR efficiency and specificity, enabling unbiased co-amplification of low copy transcripts in the presence of higher copy reference genes. As a result the qScript™ One-Step qRT-PCR Kits offer improved sensitivity over other commercially available qPCR reagents. The qScript™ One-Step Master Mix maximises the activities of both reverse transcriptase and PCR enzymes, while minimising primer-dimer formation. High specificity is assured with AccuStart™ Taq DNA Polymerase, which is bound by monoclonal antibodies for superior hot-start. Upon heating to 95 °C, the antibodies denature irreversibly releasing fully active and unmodified Taq DNA polymerase. qScript™ One-Step qRT-PCR Kits are available for all Real-Time PCR instrument platforms, including those requiring normalisation with ROX reference dye.

Ultra-Plex™ 1-Step ToughMix® is a ready-to-use, 4X-concentrated master mix for reverse transcription quantitative PCR (RT-qPCR) of RNA templates using hybridisation probe detection chemistries such as TaqMan® 5’-hydrolysis probes on Real-Time PCR systems that utilise ROX passive reference with 490 nM excitation. First-strand cDNA synthesis and PCR amplification are carried out in the same tube without opening between procedures. It is ideal for highly sensitive quantification of RNA viruses or low abundance RNA targets in uni- or multiplexed RT-qPCR applications as well as high throughput gene-expression studies. The system has been optimised to deliver maximum RT-qPCR efficiency, sensitivity, and specificity in reduced reaction volumes and fast cycle times. Ultra-Plex™ 1-Step ToughMix® contains all required components for RT-qPCR except RNA template and probe. It is compatible with all dual-labeled probe chemistries.
