GreenMastermix Low ROX optimised for realtime PCR assays in block systems that contains all components to perform quantitative PCR with the exception of primer and template DNA. This 2X Mastermix is ready-to-use and contains optimised amounts of all ingredients.
Advantages of the chemically modified SuperHot Taq polymerase used in the Genaxxon GreenMasterMix:
- Hotstart technology enables setup of PCR mixture at room temperatur
- No pipetting on ice necessary anymore
- No immediate further processing (PCR) necessary. The pipetted pre-PCR mixtures can be left at RT for up to 3 days.
- Amplification of GC-rich templates
- High yields
- No Primer dimers
The Genaxxon SuperHot Taq DNA polymerase offers convenience and practicality, without compromising efficiency or specificity:
1. The chemical modification inhibits the polymerase, which prevents false priming at all temperatures tested, allowing for PCR reactions to be set up at RT (20°C to 25°C), and
2. "High mix stability allows pre-assemby of the plate in advance", which means PCR reactions can be prepared and stored at RT for up to three days before they are run, without affecting the results.
The Green qPCR master mix high ROX contains all the necessary components in an optimized composition to carry out quantitative PCR:
- chemically modified Taq DNA Polymerase
- dATP, dCTP, dGTP, dTTP
- intercalating green fluorescent dye
- 50nM ROX
- optimized reaction buffer
- stabilizers and enhancers to enable even amplification of low copy number targets
- the small aliquote size of 1.25mL simplifies handling and storage (less freeze-thaw cycles per aliquote)
Stability at +2°C to +8°C (refrigerator): minimum of 8 months.
This Mastermix is specially suited for the following instruments: Applied Biosystems® 7500, 7500 Fast and ViiA™ 7, QuantStudio™ instruments, Agilent Mx3000P™, Mx3005P™, Mx4000™ and AriaMx.

When performing fast real-time PCR, it is of high importance to consider primer design and target size. For efficient amplification during fast cycling conditions, target size between 70 bp and 200 bp is recommended. The shorter the target length, the faster the total run time. For other targets and other primer sets, the annealing step has to be determined experimentally.
Please use the following protocol for inspiration as you need to optimize instruments settings according to yourr target size and applied instruments.
Fast real-time PCR results using Genaxxon Master Mixes on Mx3005P
GreenMasterMix Low ROXTM and ProbeMasterMix Low ROXTM were tested on Mx3005P (Agilent Technologies) using fast cycling real-time 2-step protocols; Fast Pthr Green Mx and Fast Pthr Probe Mx, respectively.
qPCR Setup: For GreenMasterMix Low ROXTM and ProbeMasterMix Low ROXTM, primers targeting Pthr (75 bp) and 4 concentrations of gDNA (40 ng, 20 ng, 10 ng and 5 ng) were used. All DNA concentrations were tested in quadruple replicates. See fig. 3 and 4. The PCR reaction mix was run on MX3005P (Requiring Low ROX). Instrument settings, run times and quality criteria for the applied fast protocols; Fast Pthr Green Mx and Fast Pthr Probe Mx, were compared to the standard protocol; Standard Pthr Mx. See table 2.
Results: The standard Fast Pthr Probe Mx protocol has a run time of 83.4 minutes. Fast Pthr Green Mx and Fast Pthr Probe Mx protocols, resulted in run times of 50.1 and 46.8 minutes, respectively. All protocol times are inclusive ramping time and a15 minutes hot start. The determined criteria, as shown in table 2, for Fast Pthr Green Mx and Fast Pthr Probe Mx protocols were acceptable. Furthermore, the melt curve analysis using GreenMasterMix Low ROXTM with Fast Pthr Green Mx protocol, confirmed high specificity.
