Combi PPP Master Mix


Combi PPP Master Mix is dedicated for simplified routinely performed hot start PCR. It contains Taq DNA polymerase, deoxyribonucleotides, reaction buffer components, additives and monoclonal antibody anti-Taq. Samples for PCR are prepared by simple mixing Combi PPP Master Mix with target specific oligonucleotide primers, template DNA and water. Additives and the dye present in Combi PPP Master Mix allow direct loading of the PCR amplified samples into the gel without adding loading buffer. When compared to PPP Master Mix (Cat. No, P124 - P126), it contains a monoclonal antibody which binds to and inactivates enzymatic activity of Taq DNA polymerase. The master mix is not recommended for any applications in which fluorescence excitation is used, such as qPCR.

Hot start

  • Combi PPP Master Mix contains anti-Taq DNA polymerase monoclonal antibody which inactivates enzymatic activity of the enzyme.  After the first denaturation cycle, the antibody is irreversibly inactivated and Taq DNA polymerase regains enzymatic activity.

Rapid samples preparation

  • All components of the Combi PPP Master Mix are 2x concentrated, which facilitates rapid preparation of the PCR samples. The samples are prepared by mixing an aliquot of  Combi PPP Master Mix with oligonucleotide primers, template DNA and H2O (included).
  • Combi PPP Master Mix is especially useful for routine analyses of large numbers of DNA samples. To 0.5 ml of the Master Mix in original tube, primers (e.g. 40 µl forward and 40 µl reverse) and PCR H2O (380 µl) are added and mixed; the "armed" Mix can be stored at -20 ± 5oC. Immediately before use, the Mix is thawed and each 24 µl aliquot is mixed with 1 µl of the tested DNA template and PCR is performed.

Direct loading into the gel

  • Combi PPP Master Mix contains additives and a dye which allow direct loading of the samples into the gel, without necessity to add loading buffer.
  • Dye present in the Mix migrates in the agarose gel in front of the primers and therefore does not interfere with quantification of the PCR products. The dye and other additives have no effect on DNA amplification during PCR.

High efficiency and specificity

  • The kit allows highly sensitive and specific amplification of corresponding DNA fragments from genomic DNA or from cDNA obtained by reverse transcription; it possesses MgCl2 at a concentration suitable for most PCRs.
  • Monoclonal antibody bound to the enzyme significantly reduces production of nonspecific PCR products.
