- The Master mix contains dTTP
- It contains EvaGreen as fluorescent dye
- The qPCR / RT-PCR Mastermix EVA 1 is ready-to-use and is optimized for high specificity and sensitivity because of optimized reaction buffer
- Easy to use because ready-to-use Master Mix
- The Master Mix can be used with ROX as reference dye (1x
concentrated)
Applications:
- Detection and quantification of DNA and cDNA targets
- Profiling gene expression
- Microbial detection
- Viral load determination
- Analysis of SNPs, mutations and methylations in PCR amplicons
The Master Mix contains all reagents required for qPCR (except template and primer) in a premixed 2x concentrated ready-to-use solution. The high specificity and sensitivity of the mix is achieved by an optimized hot-start polymerase. Its activity is blocked at ambient temperature and switched on automatically at the onset of the initial denaturation. The thermal activation prevents the extension of non-specifically annealed primers and primer-dimer formations at low temperatures during PCR setup.
Concentration: The Master mix is 2x concentrated
List of components:
Hot-Start Polymerase for qPCR, dATP, dCTP, dGTP, dTTP (0,5mM each), optimized reaction buffer with EvaGreen and 4mM MgCl2, stabilizers and

- vortex all solutions carefully before using and before PCR
- may you add the enzyme mix after Template DNA
- an individual optimization of annealing temperature may be
necessary for new combinations of primers and Template DNA
General Thermo-Cycler protocol for qPCR / RTD-PCR Master mix:
Note: working with EvaGreen just select the optical setting for FAM or SYBR Green at the cycler
