KOD One™ PCR Master Mix for Ultra-Fast PCR

What is PCR Master Mix?

PCR Master Mix is a ready-mix of PCR reagents. PCR is widely used across molecular biology labs to amplify specific fragments of DNA. Our PCR homepage provides helpful links to more information on the basics of PCR, including resources for PCR Master Mix.

PCR Master Mix takes the guesswork out of PCR by being a batch mixture of PCR reagents at optimal concentrations that can be prepared once and divided among many PCR tubes or PCR plates. It is convenient, timesaving, and preempts possible errors in mixing, making it an ideal choice for high-throughput applications.

Common applications of PCR Master Mix are high throughput PCR and routine PCR. These mixes are ideal because they circumvent reagents being entirely left out of a reaction and delivering false negatives as a result.

For more information about types of mixes and their components, please visit our PCR Master Mix page.

Introduction to KOD One PCR Master Mix

Traditional PCR can take time to complete and obtain results. Unfortunately, time is a valuable resource, especially when you have numerous samples. Fast PCR allows you to obtain your results in a shorter timeframe than traditional PCR, making it an efficient option.

The new KOD One™ PCR Master Mix offers ultra-fast PCR with one of the fastest elongation rates available for high fidelity polymerases. It uses a new genetically modified hot start KOD polymerase (UKOD) to enable ultra-fast PCR while offering the highest specificity, fidelity, and yield. The KOD One™ polymerase is made of a new DNA polymerase with a significantly faster elongation time of 5 seconds per kb (5 sec/kb) by applying both the UKOD and an elongation enhancer that is unique to this product.

The KOD One™ PCR Master Mix is a flexible product, provided in a convenient, ready-to-use format, with the ability to use it directly on crude samples like blood and mouse cell lysates. In addition to crude samples, it can be used on templates containing uracils (dU). The master mix can use primers containing both inosines (dI) and dU for amplification.

The hot start KOD polymerase is antibody-inactivated with two types of antibodies that prevent the 5' → 3' polymerase activity and 3'→5' exonuclease activities. Upon heat-activation, the 3'→5' proof-reading ability of the enzyme generates blunt-end PCR products. Features like a hot-start format for specific enzyme activity, as well as higher fidelity than most polymerases, add to the flexibility of this master mix to be used in different applications.
