Quenching Mechanisms in Oligonucleotide Probes

The efficiency of fluorescence quenching upon excitation is very distance dependent – if the reporter fluorophore and quencher are far apart, there is fluorescence; if the reporter and quencher are close together in space, fluorescence is suppressed. Continue reading to learn more about static and FRET quenching.

Genotyping - qPCR

Real-time PCR methods using fluorescent probes are ideal for end-point genotyping in low to medium throughput disease-association studies, or marker selection in industrial applications. Review the probe types we offer for this application, and learn how to design assays for genotyping.

Multiplexing qPCR

Multiplexed qPCR combines several PCR assays together into one but resolves the reactions using reporter dyes with distinct spectra. Only Biosearch offers fluorophores and quenchers that span the spectrum to maximize your multiplexing for 2-plex, 3-plex, 4-plex, and 5-plex qPCR.
