Highlights of the latest Platinum DNA polymerases

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

Common benefits of these enzymes include:
Enhanced PCR specificity—antibody-mediated hot-start enzymes with Platinum technology
Helping to 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
Simplifying 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
