Taq PCR Master Mix Kit

For convenient PCR setup using a premixed solution

  • Minimal optimization due to QIAGEN PCR Buffer
  • Master mix format for easy reaction setup
  • Fewer pipetting steps minimize the risk of contamination
Taq PCR Master Mix contains Taq DNA Polymerase, the unique QIAGEN PCR Buffer that minimizes the requirement for optimization, and dNTPs. The convenient 2x master mix format reduces pipetting steps, increasing throughput and reproducibility, while reducing the risk of contamination.

Reproducible PCR.
A fragment of the hepatitis B surface antigen gene (gene S) was amplified from 10, 20, and 50 copies of target template, using the Taq PCR Master Mix Kit. Five parallel amplifications were performed for each amount of starting template DNA. Equal volumes of the PCR products were analyzed on a 2% agarose gel. C: negative control; M: markers.
Performance
TheTaq PCR Master Mix Kit outperformed kits tested from other suppliers and ensures reliable PCR performance in a wide range of PCR applications — without the need for time-consuming optimization (see figure "Reproducible PCR"). Taq DNA Polymerase ensures highly specific amplification with different primer–template systems (see figures "Tolerance of different primer Tm values" and "Specific amplification of long PCR products"). Every lot of QIAGEN's Taq DNA Polymerase is subjected to a comprehensive range of quality control tests, including a stringent PCR specificity and reproducibility assay in which low-copy targets are amplified from human genomic DNA (see figure "Lot-to-lot reproducibility"). Due to the unique PCR buffer included in the master mix, optimization of PCR by varying the annealing temperature or the Mg2+ concentration is dramatically reduced and often not required (see figures "Wide annealing temperature window" and "Tolerance to variable magnesium concentration").

Principle

The Taq PCR Master Mix Kit includes QIAGEN's Taq DNA Polymerase in a premixed format. This ready-to-use solution also includes the QIAGEN PCR Buffer, MgCl2, and ultrapure dNTPs at optimized concentrations. Only primers and template DNA need to be added to set up PCR. Due to the convenient master mix format, pipetting errors are minimized, ensuring highly reproducible PCR results (see figure "Reproducible PCR"). Taq PCR Master Mix can be stored at 2–8°C for up to 2 months , allowing even faster PCR setup by eliminating thawing time.

Taq DNA Polymerase

Taq DNA Polymerase DNA Polymerase is a high-quality recombinant enzyme that is suitable for general and specialized PCR applications (see figures "Tolerance of different primer Tm values" and "Specific amplification of long PCR products").

QIAGEN PCR Buffer 

The innovative QIAGEN PCR Buffer has been developed to save time and effort by reducing the need for PCR optimization. QIAGEN PCR Buffer contains both KCl and (NH4)2SO4 (see figure "Increased specificity of primer annealing"). This unique buffer facilitates the amplification of specific PCR  products. During the annealing step of every PCR cycle, the buffer allows a high ratio of specific-to-nonspecific primer binding. Owing to a uniquely balanced combination of KCl and (NH4)2SO4, the PCR buffer provides stringent primer-annealing conditions over a wider range of annealing temperatures and Mg2+ concentrations than conventional PCR buffers. Optimization of PCR by varying the annealing temperature or the Mg2+ concentration is dramatically reduced and often not required (see figures "Wide annealing temperature window" and "Tolerance to variable magnesium concentration").

Procedure
Taq PCR Master Mix includesTaq DNA Polymerase, QIAGEN PCR Buffer, MgCl2, and ultrapure dNTPs at optimized concentrations. The ready-to-use 2x master mix format minimizes pipetting errors and also provides greater convenience. PCR setup is fast, easy, and straightforward — only primers and template DNA need to be added. The easy-to-follow protocol provided with the kit ensures specific amplification and PCR success at the first attempt.
