What should the starting template DNA quality and quantity be for PCR?

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
What kind of PCR products can be cloned with the QIAGEN PCR Cloning Kit?

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.


FAQ ID -165
Do you have a protocol for polyacrylamide gel analysis of oligonucleotides?
Yes, please follow the Supplementary Protocol 'Polyacrylamide_gel_analysis_of_oligonucleotides' (PCR03).
FAQ ID -961
What makes QIAGEN's 10x Taq and HotStarTaq DNA Polymerase PCR buffer superior?
The QIAGEN 10x Taq and HotStarTaq DNA Polymerase PCR buffer contains a uniquely balanced combination of KCl and (NH4)2SO4. It provides stringent primer-annealing conditions over a wider range of annealing temperatures and Mg2+ concentrations than conventional PCR buffers.
FAQ ID -566
How comparable is CoralLoad gel loading dye contained in various QIAGEN PCR Kits to Sigma Red?

CoralLoad gel tracking dye contained in Taq, HotStarTaq, TopTaq DNA Polymerase and TopTaq Master Mix Kits separates into 2 fragment-size dependent colors (orange and red) when loaded onto an agarose gel. Sigma Red buffer only has one color which is harder to visualize.



FAQ ID -1644
Have you tested the effect of inhibitors on PCR performance?

Yes. Please see Table 3 in our brochure Maximizing PCR and RT-PCR success. We tested the effects of different inhibitory substances in a number of PCR systems. We also analyzed the effect of including different volumes of reverse transcription (RT) reaction mixtures in PCR. Please see the table below for a list of commonly encountered template impurities and their inhibitory effects on PCR.


Impurities showing inhibitory effects on PCR

Substance Inhibitory concentration
SDS >0.005% (w/v)
Phenol >0.2% (v/v)
Ethanol >1% (v/v)
Isopropanol >1% (v/v)
Sodium Acetate ≥5 mM
Sodium Chloride ≥25 nM
EDTA ≥0.5 mM
Hemoglobin ≥1 mg/ml
Heparin ≥0.15 i.U./ml
Urea >20 mM
RT reaction mixture ≥15%



FAQ ID -818
Can QIAGEN's Taq- and HotstarTaq DNA Polymerases be used for cycle sequencing?
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
How can one determine the optimal annealing temperature for a specific PCR assay?

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.
