WebWhen an oligonucleotide probe is cleaved by the AmpliTaq Gold DNA Polymerase 5′ nuclease activity, the quencher is separated from the reporter dye increasing the fluorescence of the reporter. Accumulation of PCR products can be detected in real time by monitoring the increase in fluorescence of each reporter dye at each PCR cycle. Dark quenchers are dyes with no native fluorescence. Until the last few years, quenchers have typically been a second fluorescent dye, for example, fluorescein as the reporter and tetramethyl-rhodamine as the quencher (FAM/TAM probes). However, quencher fluorescence can increase background noise due to overlap between the quencher and reporter fluorescence spectra. This limitation often necessitates the use of complex data analysis and optical filters. Dark quencher… offices jobs hiring

WebFeb 11, 2005 · The unmodified DNA probe is called “ODN.”. Various fluorescent dyes (F) and quenchers (Q) are covalently attached at the probe ends. Modified probes are designated F-ODN-Q to indicate relative position and type of the label from 5′- to 3′-end. The terms “label” and “modification” apply to both fluorophores and quenchers.
