IP-free BHQ® quenchers for all applications
By purchasing your BHQ® labeled oligonucleotides and qPCR Probes from Eurogentec you can use them for diagnostic and commercial applications without license fees.
Unique Partner for all your applications
By ordering your BHQ® probes from us, you will benefit from our know-how, our experience and the quality of the original BHQ® quenchers. We are your unique partner all along your project, from your initial research and development phase to the commercial application.
BHQ-1®, BHQ-2® and BHQ-3®
We use the original Black Hole Quencher 1, 2 and 3 to label your oligonucleotides. BHQ® quenchers are the most popular and used quenchers for fluorescence quenched qPCR probes as they absorb a wide range of wavelengths from 480 nm to 730 nm.
|BHQ® Quenchers||Absorption Range (in nm)||IP Free D/Q pairs||Compatible fluorescent dyes|
|● Black Hole Quencher 1||480 – 580 nm||
Yakima Yellow/ BHQ®-1
|● Black Hole Quencher 2||559 – 690 nm||

Why choose BHQ® quenchers?
IP free for all applications
BHQ® patents for diagnostic and commercial use were lifted.
No native fluorescence
BHQ® were engineered to be true black quenchers with no native fluorescence.
Efficiently quenched fluorescent Dyes
BHQ® quench fluorescence with a very high signal-to-noise ratio.
Broad absorption range
BHQ® absorb fluorescent emission from 480 nm to 730 nm
Compatible with a large range of reporter dyes
BHQ® can be paired to a large panel of fluorescent dyes
Ideal for multiplexing assays
BHQ® have no residual background signal and a broad spectral range
Diagnostic Grade Oligonucleotides
Pre-diagnostic and diagnostic grade oligonucleotides can be ordered after introducing a request.
Upon request you will be in contact with your dedicated account manager to discuss your project. After discussion and evaluation we will emit a quote for you.
Once we receive your agreement and the quote is signed, we will start the production of your nucleic acid sequences.
Other IP-Friendly Dyes
Our portfolio of Access™ fluorescent Dyes and Quenchers is comprehensive, spanning the full visible spectrum. We have D/Q pairs covering all the qPCR channels from Deep Blue to Infrared.
