Figure 1: Taq PCR Master Mix - Package Contents
  • Taq PCR Master Mix [2x] (1.5 mM MgCl2 final conc.)
  • PCR grade water
  • 10x Color Load (optional dye mix for direct gel loading)
25 mM MgCl2 solution for fine tuning of Mg++ ion concentration can be included upon customer's request. If required, please ask us to ship this component along with your order.

  • All-Purpose Master Mix: 2x PCR Master Mix complete with optimized reaction buffer and high quality dNTPs.
  • Additional Package Contents: Plus PCR pure water and plus optional Color Load Buffer for direct post-PCR gel loading, both provided in separate tubes, respectively.
  • High Quality: Same high enzyme purity and enzymatic activity as → Taq DNA Polymerase [Cat No. E2500]).
  • Strict Quality Control: Same stringent quality control as specified for → Taq DNA Polymerase [Cat No. E2500]).
  • Optimized for Advanced Standardization Levels: Minimizes pipetting errors: Warrants high reproducibility for critical PCR assays.
  • Continuous Reproducibility: Stable, reproducible high performance for more than 25 freeze-thaw cycles.
  • Free of Contaminating DNA: No residual PCR-amplificable DNA present, as tested with many different amplification targets (including bacterial 16S rRNA genes).
  • No false positives.
  • Careful and Elaborate Purification: High purity and enzymatic activity as a result of thorough but careful and gentle enzyme purification.
  • Enzyme Properties: Intrinsic exonuclease activities: 5'-3' present, 3'-5' none. No proofreading activity.
  • Cloning: Enables both TA- and blunt end cloning.
  • Also available as: → Taq DNA Polymerase (Non - Master Mix) [Cat No. E2500]).
Application Examples

Figure 2: Comparisonal PCR amplification of an 1.1 kb amplicon (human ccr5 gene) with Taq DNA Polymerase (Cat. No. E2500, non-master-mix format)) and ready-to-use Taq PCR Master Mix (Cat. No. 2520). Molecular weight marker MW (Perfect™ 1kb DNA Ladder). Each PCR reaction: 1.25 U Taq DNA Polymerase, 0.2 mM dNTPs; 50 µl reaction volume. Lanes 2-3: EURx Taq DNA Polymerase (non-master-mix format); 4-5: EURx Taq PCR Master Mix (after 25 freeze-thaw cycles, to demonstrate tolerance for repeated freezing and thawing), 6-7: EURx Taq PCR Master Mix (after 25 freeze-thaw cycles) plus optional Color Load (for direct post-PCR gel loading).
