Black hole quencher dyes
WebBlack Hole Quencher®-1 (BHQ-1) and Black Hole Quencher®-2 (BHQ-2) differ in the spectrum they are able to absorb. BHQ-1 is used to quench green and yellow dyes, such as FAM, TET, and HEX. BHQ-2 is preferred for quenching orange or red dyes, such as TAMRA™, Texas Red®, and Cy™ 5. • Dabsyl (dimethylaminoazobenzenesulfonic acid) absorbs in the green spectrum and is often used with fluorescein. (Dabsyl has a nearly identical absorption, but has a sulfonyl chloride to form more stable conjugates, instead of a succinimidyl ester). • Black Hole Quenchers are capable of quenching across the entire visible spectrum.

http://www.confluore.com/product/PNOBCP-57.html WebBHQ-2 is used to quench in the range 550 – 650 nm and is most effective in quenching fluorophores such as TAMRA, ROX, Cyanine-3, Cy3, Cy3.5™ and Red 640. We also offer Black Hole Quenchers for labelling peptides. All of our BHQ dyes are available as carboxylic acid or succinimidyl esters.

WebSep 30, 2024 · Dithiothreitol (DTT is a strong reducing agent capable of reducing the azo linkages present in BHQ™ (Black Hole Quencher™) dyes. Reduction of the azo bond in the BHQ dye results in a loss of quencher activity. Loss of quenching appears as increasing fluorescence and the background is then observed to increase, evident as baseline drift. WebBHQ dyes are robust dark quenchers that very nicely complement our existing product line. They are compatible with ammonium hydroxide deprotection, exhibit excellent coupling efficiencies, have large extinction coefficients and are completely non-fluorescent.
