Eurogentec
Custom qPCR probes
Dual labeled oligo synthesis
Since 1985, as a recognized oligo synthesis company, Eurogentec have been producing a wide range of custom Taqman® Probes. Their extensive portfolio of fluorescent dyes and NFQ quenchers allows our dual-labeled probes to be utilized across any qPCR channels, from deep blue to infrared. In addition to classical fluorophores and quenchers like HEX, FAM, TAMRA, and BHQ®, they offer custom qPCR probes labeled with our proprietary dyes (HiLyte™ Fluor, QXL®) using an IP-friendly approach for commercialization.

You are no longer limited by any license! Use MGB Probes manufactured at Eurogentec for any application all around the world.
Benefits
MGB increases the Tm of a probe thanks to its minor groove binding ability.
MGB probes are more specific, more efficient and more sensitive than standard double-dye probes.
- Sensitive detection : High signal to noise ratio
- Delivered quantities : 6 - 20 - 50 nmol (Larger quantities on request)
- Complete offer : More than 15 Dyes available, covering all qPCR channels
- Free Wobble bases : Available at no additional cost
MGB-probe principle
MGB Probes have a fluorescent reporter dye and a quencher at their 5’ and 3’ ends, respectively.
During the amplification process, the 5’>3’ exonuclease activity of the Taq DNA polymerase cleaves the fluorophore from the probe. Since the fluorophore is no longer subjected to FRET quenching, it starts to fluoresce. This fluorescence can be measured, and the level is directly proportional to the amount of target DNA accumulating during the PCR reaction.

Molecular beacons principle
Molecular Beacons are specialized probes featuring a stem-loop structure with a fluorophore at the 5’ end and a quencher at the 3’ end. The stem sequence holds the fluorophore and quencher in close proximity, preventing fluorescence in the absence of a complementary sequence to the loop region. In this state, any photons emitted by the fluorophore are absorbed by the quencher.
When a complementary target sequence is present, the probe unfolds and hybridizes with the target. This separates the fluorophore from the quencher, allowing the fluorophore to emit light. The resulting fluorescence is directly proportional to the amount of target sequence present and is measured in real-time, enabling the quantification of the target sequence.
