Obtain high quality qPCR results using PrimeTime™ Gene Expression Master Mix

2X solution for probe-based qPCR assays

Product spotlight: If you are doing 5′ nuclease assays for qPCR or 2-step qPCR, use this versatile master mix in both singleplex or multiplex. It is compatible with a wide range of instruments, works under standard or fast cycling conditions, and can be used with or without a range of reference dyes.

Reverse transcription quantitative PCR (RT-qPCR) is the method of choice for accurate and fast gene expression analysis. With more and more researchers relying on PrimeTime qPCR Probes and custom assays, we recognized the need for a quality gene expression master mix to accompany these products.

PrimeTime Gene Expression Master Mix is a versatile and convenient master mix for 5′ nuclease assays. It has been designed for qPCR and 2-step RT-qPCR using PrimeTime qPCR Probe Assays, but also can be used with primer-probe sets from IDT and other manufacturers. In addition, this master mix is compatible with a wide range of instruments—whether you prefer standard or fast cycling conditions, and whether or not you need a reference dye.

Useful for high-throughput or overnight applications

PrimeTime Gene Expression Master Mix has been formulated for use at room temperature, so you can let your reactions cycle overnight or perform automated, high-throughput experiments (Figure 1). Cq values were consistent when qPCRs were run immediately or after 24 hr at room temperature. The standard deviations for the Cq values were <0.5 for template levels >10 copies. This result was obtained with 3 different lots of master mix, so you can rely on this reagent to provide reliable results when used in your qPCR assays.

Consistent results at 0 and 24 hrs across different lots of PrimeTime Gene Expression Master Mix
Figure 1. Consistent results at 0 and 24 hours across different lots of PrimeTime Gene Expression Master Mix. qPCR mixes of PrimeTime HPRT qPCR Assay (Assay ID: Hs.PT.58v.45621572), PrimeTime Gene Expression Master Mix (from 1 of 3 lots), reference dye, and varying amounts of gBlocks™ Gene Fragments (10–107 copies; 8 replicates) were assembled. A JANUS® automated, liquid-handling workstation (PerkinElmer) was used to load the reactions into PCR plates. Reactions were run immediately (Day 0) or after 24 hours (Day 1) on a QuantStudio™ 7 Flex System (Thermo Fisher Scientific).
