PCR Enzymes & Master Mixes

Choose from a variety of stand-alone PCR enzymes and master mixes optimized for your applications and experimental needs. 

PCR master mix

Our new generation of Platinum DNA polymerases come with novel buffers enabling universal primer annealing at a temperature of 60°C. The universal primer annealing allows all primers to anneal to the template DNA at 60°C, eliminating Tm calculations and enhancing convenience. A combination of the innovative buffers, high-performing enzymes, and reliable hot-start technology offers exceptional PCR results, even in the toughest applications.

A PCR master mix is a pre-mixed solution that contains a thermostable DNA polymerase, dNTPs (deoxynucleotide triphosphates), buffer, and other additives. The optimized master mix formulation helps ensure consistent and reliable results, save time, and reduce the potential for errors during reaction set up. In addition, PCR master mixes can be an economical choice compared to purchasing individual enzymes and reagents.

Hot-start PCR

Hot-start PCR is a type of PCR where DNA polymerase activity is inhibited until the initial denaturation step. This inhibition is achieved through various methods, such as antibodies, affibodies, or chemical modifications of the polymerase. The benefits of hot-start PCR include increased specificity and yield.

Taq DNA polymerases: Native and recombinant enzymes

Native DNA polymerases are naturally occurring enzymes found in various organisms such as bacteria and archaea. Taq DNA polymerase is one of the best-known thermostable DNA polymerases used in PCR amplification of DNA targets. The native enzyme is purified from Thermus aquaticus YT1. The native Taq DNA polymerase is often preferred for amplification of bacterial DNA sequences homologous to E. coli sequences. The recombinant enzyme is a cloned version of native Taq polymerases with improved properties and functionalities.


Platinum DNA polymerases for excellent results

The new generation of Platinum DNA polymerases come with novel buffers, enabling primer annealing at a universal temperature of 60°C. A combination of the innovative buffers, high-performing enzymes, and reliable hot-start technology offers exceptional PCR results even for challenging applications.


Benefits of platinum PCR enzymes

  • Enhanced PCR specificity—Antibody-mediated hot-start enzymes with Platinum technology
  • Circumvent multiple PCR runs—Ability to co-cycle different PCR assays
  • Detecting multiple targets from one template—Ability to multiplex up to 15 targets
  • Fewer steps for pipetting and reagent setup—Necessary reaction components and direct gel-loading dyes included in the green master mixes
  • Simplify PCR optimization steps—Protocol with a universal annealing temperature
  • Robust PCR with difficult targets—High tolerance to inhibitor-containing samples and efficient amplification of GC-rich sequences
  • Enabling automation or robotic setup—Assembled reactions stable on the benchtop for 8–24 hours
