General description

The PCR Optimization Kit is the convenient and reliable solution for optimizing PCR experiments. It contains a set of buffers with different pH and magnesium concentrations spanning the most often-used reaction conditions. Four different additives allow additional optimization to increase yield and specificity.
The optimal reaction conditions of a PCR experiment depend on the template DNA and the respective primer pair. The main parameters that may vary between different applications are the magnesium concentration, pH of the reaction buffer, and the temperature and time of the different cycling steps. Additionally, various additives may increase the specificity and yield of some applications.
Therefore, it is generally recommended to optimize PCR conditions for each new template/primer pair. However, the preparation of the various solutions is time-consuming and may increase the risk of contamination. This is where the PCR Optimization Kit can help in optimization.


With the ready-to-use solutions supplied in the PCR Optimization Kit the best PCR conditions can be determined by easily varying MgCl2 concentration, the pH of the buffer, and additives like DMSO or glycerol. DMSO, for instance, is reported to reduce nonspecific priming, while gelatin and glycerol stabilize Taq DNA polymerase during PCR, which generally increases the yield. The ready-to-use solutions save time for your research and minimize the risk of contamination. In combination with Roche′s FastStart High Fidelity PCR System this kit allows you to define optimal conditions for multiplex PCR experiments with astonishing results.


1 kit containing 6 components.


Each lot of the PCR Optimization Kit is function tested in PCR using human genomic DNA for the absence of contaminating DNA, and exo- or endonuclease activity according to the current Quality Control procedures.
