Features

QIAGEN PCR Buffer for minimal optimization
쉽고 간편한 조작을위해 format 선택이 가능함
Fewer pipetting steps minimize the risk of contamination

Product Details

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.

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 ""). Taq DNA Polymerase ensures highly specific amplification with different primer–template systems (see figures "" and ""). 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 ""). 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 "" and "").

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 T_m 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").

FAQ

Both the quality and quantity of nucleic acid starting template affect PCR, in particular the sensitivity and efficiency of amplification. PCR sensitivity and efficiency can be reduced by the presence of impurities in nucleic acid preparations or in biological samples. These PCR inhibitors are completely removed when template is prepared using QIAGEN Kits for nucleic acid purification. Please refer to the Brochure "Maximizing PCR and RT-PCR success" for additional information.

The optimal primer–template ratio has to be determined empirically. If too little template is used, primers may not be able to find their complementary sequences. Too much template may lead to an increase in mispriming events. Generally, no more than 1 ug of template DNA should be used per PCR reaction. As an initial guide, spectrophotometric and molar conversion values for different nucleic acid templates are listed below.

FAQ ID -74

PCR products that will be cloned using the QIAGEN PCR Cloning Kit should be generated using a thermostable DNA Polymerase without proofreading activity, such as Taq DNA Polymerase. Such polymerases attach a single A overhang to their reaction products, which can hybridize to the U overhang of the pDrive Cloning Vector. For efficient addition of an A overhang during the PCR procedure, we recommend a final extension step for 10 min at 72°C as described in the standard protocols of the Taq PCR- and HotStarTaq PCR handbook.

Taq DNA Polymerase and HotStarTaq DNA Polymerase are compatible with cycle sequencing. However, our buffer system is not optimized for this purpose. Optimization of reaction conditions is therefore required when using these Polymerases for cycle sequencing. Unfortunately, we do not have any protocols for this application. An initial activation of the enzyme is necessary if HotStarTaq DNA Polymerase is used.

FAQ ID -741

To determine the optimal annealing temperature for a PCR assay, a Temperature Gradient experiment should be performed. To do this, you will set up several PCR reactions in duplicate for the same primer/template combination, using the same PCR chemistry, and subject each of the reactions to a slightly different annealing temperature within a specified range. If a thermal cycler with a temperature gradient function can be used, you can simply program a temperature range for adjacent wells in the cycling block. If no cycler with a gradient function exists in your lab, you will either have to perform duplicate reactions at different temperatures in different machines (if available), or back to back in the same machine.
