Quencher

BHQ-1 Probes

DNA probe Quencher BHQ-1 absorbs wavelenght between 480-580 nm.

BHQ-1 quencher for DNA probes is known for its large absorption range. Black Hole Quencher-1 is an excellent partner for many reporter dyes. Since it does not fluorescence itself, very little background noise is produced. This makes signal detection of the reporter even more accurate.

So-called FRET (fluorescence resonance energy transfer) probes are based on the principle that the quencher, in the close proximity of a reporter, absorbs emittied wavelength. At this point, reporter signal is absorbed in large part. Only when the reporter moves away from the quencher its emission can be fully detected.

Usually, a quencher is synthesized at the 3′-end of a DNA sequence. Thanks to its biochemical properties, the modification can be included in the normal process of DNA synthesis.

On our BHQ-1 microfluidic chip¬† for the Kilobaser, the BHQ-1 is anchored to the CPG material of the microcolumn. This ensures that the synthesis has a quencher at the 3′-end as desired. In combination with a suitable reporter, such as the 6-FAM fluorescent dye at the 5′-end of the DNA probe, many applications become possible.
