Plain Combi PP Master Mix


Plain Combi PPP Master Mix is a modification of Combi PPP Master mix (Cat. No. C208 - C210) not containing loading dye. This Mix is first choice for those applications where loading dye would interfere with measurements of DNA products e.g. by capillary chromatography or real-time PCR. The mix contains Taq DNA polymerase, deoxyribonucleotides, reaction buffer components, additives and anti-Taq DNA polymerase.

Hot start

  • Plain 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. This reduces amplification of nonspecific products .

Rapid preparation of PCR samples

  • All components of the Plain Combi PPP Master Mix are 2x concentrated, which facilitates rapid preparation of the PCR samples. The samples are prepared by mixing an aliquot of Plain Combi PPP Master Mix with oligonucleotide primers, template DNA and H2O (included). For qPCR analysis it is necessary to add fluorescent DNA-binding dye (such as SYBR Green I) or TaqMan probes.
  • Plain 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

  • Plain Combi PPP Master Mix contains additives which allow direct loading of the samples into the gel, without necessity to add loading buffer.

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

Technical data

Components and packaging
