Simple, Sensitive Probe-Based qPCR and RT-qPCR
The GoTaq® Probe qPCR and RT-qPCR Systems are ready-to-use 2X master mixes that simplify reaction assembly for qPCR using hydrolysis probe detection. These real-time qPCR systems are designed for sensitive detection and quantification of a broad range of DNA or RNA targets in the presence of a wide range of PCR inhibitors.
Rapid hot-start activation and processive enzymes make the GoTaq® Probe qPCR and RT-qPCR Systems compatible with most real-time PCR instruments using standard or fast cycling. Convenient, room-temperature setup makes it easy to scale up to automated and high-throughput detection formats.

Sensitivity and Specificity for qPCR
The GoTaq® Probe qPCR Master Mix is a ready-to-use, stabilized, 2X formulation with all of the components for quantitative PCR (qPCR). Just add template, primers and probe. Optimized for fast and reproducible quantitative PCR assays in the hydrolysis probe detection format, the master mix contains GoTaq® Hot Start Polymerase, MgCl2, dNTPs and a proprietary reaction buffer. The master mix does not contain a reference dye; a separate tube of CXR reference dye is included.
The GoTaq® Probe qPCR Master Mix offers:
- Sensitive detection for earlier quantitation of low- and high-copy targets over a broad dynamic range.
- Optimized formulation compatible with running multiplex assays.
- Room-temperature setup, making it suitable for automation and high-throughput detection.
- Resistance to a wide range of PCR inhibitors.

qPCR amplification from FFPE samples with GoTaq® Probe Master Mix. DNA (10ng) from a lung tumor FFPE sample was amplified under both standard and Fast thermal cycling conditions on a Roche LightCycler 480 instrument using a 384-well plate. Equivalent Cq values were observed for the three genes evaluated regardless of cycling conditions used for the experiment.
Reverse Transcription and qPCR in One Reaction
The GoTaq® Probe 1-Step RT-qPCR System enables detection and relative quantification of RNA expression levels using a one-step RT-qPCR method, combining GoScript™ Reverse Transcriptase and GoTaq® Probe qPCR Master Mix in a single-step real-time amplification reaction.
The GoScript™ RT Mix for 1-Step RT-qPCR (50X) combines optimized quantities of GoScript™ Reverse Transcriptase, RNasin® Plus RNase Inhibitor and additives to enhance single-step reactions. The GoTaq® Probe qPCR Master Mix includes dUTP. When dUTP is incorporated into the amplification products, the amplicons are susceptible to degradation by uracil-DNA glycosylase (UNG); allowing users to incorporate UNG into subsequent reactions for control of possible carryover contamination.

Expression levels for the Zmm19 gene in corn. Expression was evaluated via 1-step RT-qPCR using the GoTaq® Probe 1-Step RT-qPCR System (Cat.# A6120).
Two-Step Reverse Transcription and qPCR
The GoTaq® Probe 2-Step RT-qPCR System facilitates detection and relative quantification of RNA expression levels via a two-step RT-qPCR method using integrated components: GoScript™ Reverse Transcription System and GoTaq® Probe qPCR Master Mix.
The GoTaq® Probe qPCR Master Mix contains GoTaq® Hot Start Polymerase, MgCl2, dNTPs and a proprietary reaction buffer. The master mix does not contain a reference dye; a separate tube of CXR reference dye is included.
The GoScript™ Reverse Transcription System includes an optimized reaction buffer and M-MLV reverse transcriptase designed to enable efficient synthesis of first-strand cDNA in preparation for PCR amplification. The cDNA product can be added directly to downstream qPCR amplification reactions.
