Applied Biosystems™ TaqMan™ QSY and QSY2 Probes

Features of TaqMan QSY and QSY2 probes include:

• Cyanine 5 (Cy5) and Cyanine 5.5 (Cy5.5) reporter dyes—new TaqMan QSY2 probes include Cy5 and Cy5.5 reporter dyes, now enabling you to multiplex up to six targets
• Increased sensitivity compared to probes from another leading supplier—detect low-abundance targets, impurities, and fluctuations in bioproduction more accurately
• Multiplexing performance without compromise—use QSY for multiplexing up to four targets with ABY, JUN, FAM, and VIC and use QSY2 for 5th and 6th target multiplexing with Cy5 and Cy5.5
• Better performance retention when scaling up—consistent performance from singleplex to 6-plex creates a smoother assay development experience
• TaqMan QSY and QSY2 probes have greater dynamic range compared to probes from another leading supplier—enables more accurate detection of a greater range of analyte concentrations
• Get started quickly—BHQ probe sequences can be converted to QSY and QSY2 versions with no redesign needed
• Compatible with our master mixes and validated on our instruments—get increased confidence in the performance of the probes in your lab to help get your products to market faster
• Part of the Thermo Fisher Scientific qPCR ecosystem—our teams can support you in all components of the real‐time PCR (qPCR) workflow
