New Applied Biosystems TaqMan QSY2 probes enable multiplexing of research assays
April 2, 2024
The new Applied Biosystems TaqMan QSY2 probes from Thermo Fisher Scientific demonstrate improved assay performance retention when transitioning from single-plex to six-plex.
The TaqMan QSY2–quenched probe is a new quencher that enables lower background and greater signal to noise ratio with TaqMan 5’ nuclease qPCR probes. Equipped with the Cyanine 5 and Cyanine 5.5 long wavelength dyes, these probes enable 5th and 6th target multiplexing in the far-red spectrum. In head-to-head studies with their counterparts, TaqMan QSY and QSY2 probes demonstrate greater sensitivity, more dynamic range, and better performance retention when scaling from single-plex to six-plex.
Key applications:
- Microbial pathogen detection in clinical research labs
- Detection of impurities and fluctuations for bioproduction processes in Pharma/Biotech R&D and QC labs
- Gene expression studies in academic research labs
