qPCR with probes .
Our new primaQUANT PROBE ADVANCED qPCR Master Mixes have been redesigned from the ground up to deliver outstanding performance. They provide reproducible results with all common probe systems even under difficult conditions and are ideally suited for multiplex assays.
Due to its temperature stability, the primaQUANT PROBE ADVANCED Master Mix can be pipetted unrefrigerated as well as stored at room temperature for days or in the refrigerator for weeks.
Hard Facts .
Our primaQUANT Probe qPCR Master Mixes are suitable for all common types of probe assays:
- Primer probes
- Hydrolysis probes (TaqMan, MGB-TaqMan, Snake Assay)
- Hybridization probes (Hybprobe or FRET, Molecular Beacons, HyBeacon, MGB-Pleiades, MGB-Eclipse, ResonSense, Yin-Yang or displacing);
- Nucleotide analogs (PNA, LNA, ZNA, non-natural bases: Plexor primer, Tiny-Molecular Beacon).

The primaQUANT Probe qPCR Master Mix is perfect for genotyping using probes. Multiplexing allows several markers to be detected in parallel.

To determine the expression of a gene (gene or RNA expression), the total RNA must first be transcribed into cDNA.
If you want to perform cDNA synthesis in a separate step, our primaREVERSE RT kit first choice.
Alternatively, you can also transfer the RNA directly into our primaQUANT 1STEP RT-qPCR Kit.
Multiplex qPCR assays use multiple target-specific probes in parallel, each labeled with a different fluorescent dye. In this way, the expression values of several targets or genes can be determined in parallel in a time-saving manner. This elegant method is widely used, especially in diagnostics.

Quantitative PCR is also frequently used for the diagnosis of pathogens.
DNA pathogens (DNA viruses, bacteria, fungi) can thus be analyzed directly. For RNA viruses, e.g. SARS-COV2, a transcription of RNA into cDNA is necessary. Our primaREVERSE RT cDNA Synthesis Kit is ideally suited for this purpose. You can also use our primaQUANT 1-STEP Master Mix to perform cDNA synthesis and qPCR in one step.
Because of their high purity, our primaQUANT Master Mixes are ideal for detecting or ruling out contamination of a product with nucleic acids or nucleases.
Smart Package Size .
No more annoying aliquoting!
Our Master Mixes come in units of 1 ml as standard.
This is very convenient and practical, because one tube is enough for exactly one 96 well plate, two tubes for one 384 well plate. If you ever need less, you can simply store the mixes in the refrigerator for several weeks.
Customized fillings: As the manufacturer, we can of course supply you with fillings and mixtures according to your special requirements.
