New multiplex qPCR solution helps you get more data from your samples
Multiplex qPCR is a simple, efficient, and cost effective solution for overcoming the challenges of limited samples and costly analysis. Successful multiplex qPCR enables the amplification of more than one target in a single reaction using different reporters with distinct fluorescent spectra and making it possible for you to use less of your precious samples in each experiment.
We are proud to offer a complete multiplex qPCR solution that enables you to perform up to a 4-plex reaction for gene expression and a duplex reaction for genotyping analysis. Our solution includes up to four dyes optimized to work together with minimal spectral overlap, a TaqMan custom probe with a new QSY quencher, a range of qPCR master mixes, and spectral calibration plates. These, combined with our custom services and real-time PCR instruments and software, decrease the amount of time required to optimize your multiplex qPCR.

Design your own multiplex qPCR primers and probes
The TaqMan Multiplex solution consists of five components:
ABY and JUN dyes, combined with FAM and VIC dyes, provide a set of four dyes whose spectral wavelengths are closely aligned with the filter channels found on Applied Biosystems instruments.
The TaqMan quencher, QSY, is now available for optimal high-level multiplexing with best performance in 3 and 4-plex reactions.
Applied Biosystems TaqMan Multiplex Master Mix, TaqMan Fast Virus 1-Step Multiplex Master Mix (No ROX), TaqPath 1-Step Multiplex Master Mix* , and TaqPath ProAmp master mixes* are formulated to allow all amplifications to proceed despite the competition between reactions. To enable flexibility with dye options, you can choose between formulations without ROX dye or with Mustang Purple dye, an alternate passive reference dye that is used for normalization.
Calibration plates are available in different formats, and are suitable for use with the following real-time PCR systems: the QuantStudio instrument portfolio, the ViiA 7 system, and the 7500 and 7500 Fast real-time PCR systems.
Benefits to multiplexing
Multiplex qPCR allows you to get more information out of a single reaction. This is particularly important when your sample input is limited or when you need to minimize sample-analysis costs.
Multiplexing provides a way to reduce reaction costs by as much as 40%. The relative costs for the multiplex reaction are much closer to those for a singleplex reaction and offer substantial savings when compared to the costs of performing 4 singleplex reactions independently.
Workflow to develop and optimize your multiplex reaction
Determine your probe options
When starting a new project, we recommend designing your assays using TaqMan QSY probes and the FAM, VIC, ABY, or JUN reporter dyes. See the TaqMan Multiplex Optimization guide for design recommendations and advice on optimizing your multiplex qPCR experiments.
Redesign and order assays, primers, and probes
Redesign: Use Primer Express™ software and TaqMan Multiplex Optimization guide recommendations to design primers and TaqMan QSY probes, or contact Custom Services to redesign your assays.
Reorder: We recommend ordering primers and probes separately, as individual oligonucleotides and probes, to facilitate the optimization of your multiplex qPCR experiments.
Contact: Technical Support if you need information to reorder assays with alternate dyes, or if your require assistance to redesign your assays with TaqMan QSY probes (additional fees apply).
Choose and order the appropriate master mix
Use TaqMan Multiplex Master Mix or for 1-step reactions choose TaqPath 1-Step Multiplex Master Mix .
Optimization
Once you have the reagents necessary for your multiplex qPCR experiment, you can use the TaqMan Multiplex Optimization guide to optimize your gene expression and genotyping experiments.
