What do TaqMan probes do?
TaqMan genotyping assays are used to amplify and detect specific alleles in genomic DNA (gDNA). The exonuclease activity of AmpliTaq Gold® DNA Polymerase cleaves only probes hybridized to the target. Cleavage separates the reporter dye from the quencher dye, increasing fluorescence by the reporter.
How much does a TaqMan probe cost?
TaqMan – Molecular Beacons – Fluorescent Molecular Probes
| Fluorescent Probes Price List Summary* and PAGE Purified Yield** | ||
|---|---|---|
| 50 nmol scale | 1 umol scale | |
| 5′-Hex, Tet, Cy 3 or Cy 5/Quencher | $230.00 | $450.00 |
| Cy3.5, Cy5.5/Quencher | $390.00 | $650.00 |
| Cy7-NHS, 5′-NHS Dyes (Rox, AF Dyes, other)/Quencher | $410.00 | $750.00 |
Where do TaqMan probes bind?
The probes bind to the polymorphic site of interest during the annealing phase of the PCR reaction. In the extension phase of PCR, the 5′ nuclease activity of Taq polymerase will cleave the 5′ reporter dye from the perfectly hybridized probe, resulting in increased fluorescence.
What is the ideal length of primers?
A good length for PCR primers is generally around 18-30 bases. Specificity usually is dependent on length and annealing temperature. The shorter the primers are, the more efficiently they will bind or anneal to the target.
How expensive is qPCR?
One such experiment would cost: 50 EUR (or 85.78 USD) using a 96-well qPCR cycler – 96 reactions (0.72 EUR / 0.89 USD per reaction) 60 EUR (or 167.86 USD) using a 384-well qPCR cycler – 384 reactions (0.36 EUR / 0.44 USD per reaction)
How much does qPCR Cost per sample?
