Buffers

 

Multiple factors play an important role to gain reliable PCR results. Besides the DNA quality and the PCR instrument itself, choosing the right buffer is essential for creating an optimal environment when performing PCRs.

To match with your desired PCR assay conditions and applications, several Tris-based solutions are available in different compositions, such as with and without Mg2+, Tween 20 or Triton X-100. This way, it makes it easy to choose the right combination of DNA Polymerase/buffer or Master Mix for your personalized PCR reaction.

 

We recommend to use ammonium buffer for most PCR reactions. It favours high yield, steady amplification and also high specificity. For an overview of all of our buffers, download our brochure

 

 

Ammonium Buffer

 

We recommend to use ammonium buffer for most PCR reactions. Besides that it favours a high PCR yield, steady amplification and comes with high specificity, it minimises the need for optimization of annealing temperatures and/or Mg2+ concentrations. Ammonium buffer also works well when working with difficult templates, such as GC-rich DNA sequences.

 

Features

  • Promotes amplification on most DNA templates

  • High yield & specificity Picture: “Ampliqon 10x Ammonium Buffer, 15 mM”

  • Tolerance for primer annealing temperatures

  • 10X buffer

 

Available in 4 options:

  • 15 mM MgCl2

  • Mg2+ free

  • Tween free

  • Mg2+ & Tween free

 


Ammonium Buffer: Minimal need for optimisation.

A broad range of Mg2+ concentrations and temperatures results in specific products with high yield (lanes 1.5 – 2.5 and lanes 57 – 66).

In the left part, a Mg2+ dilution series is shown from 0.5 – 4.5 mM Mg2+ at 60°C. The right part shows a temperature gradient from 51 – 66°C at 1.5 mM Mg2+. M: marker.

 

TIP – CHOOSE THE RIGHT BUFFER

We recommend using Mg2+ free buffer if you need to optimize your PCR protocol, especially if Mg2+ concentrations lower than 1.5 mM are required in your set-up.

Standard Buffer

Although we recommend using ammonium buffer, when you already have optimised your PCR protocols for this buffer, we recommend to keep using the Standard Buffer.

The buffer is based on potassium and has a high specificity. Nevertheless, it usually needs optimisation regarding primer annealing temperatures and Mg2+ concentrations.

DNA templates with a high purity are desired in combination with this buffer.

Standard Buffer: Optimisation is needed.

A narrow range of Mg2+ concentrations and temperatures results in specific products (lanes 1.5 – 2.0 and lanes 60 – 66).

TIP – CHOOSE THE RIGHT BUFFER

We recommend to use ammonium buffer for most PCR applications. High yield can be expected and minimal optimisation is needed regarding annealing temperatures or Mg2+ concentrations.

We recommend using Mg2+ free buffer if you need to optimize your PCR protocol, especially if Mg2+ concentrations lower than 1.5 mM are required in your set-up.

We recommend using detergent free buffers if fluorescent spectrometry is involved in automation and downstream applications.


 

Combination Buffer

 

Combination Buffer is a balanced formulation ammonium-potassium PCR buffer which results in high product yield and good specificity. This buffer shows good results on several PCR instruments and is worth testing when setting up a new protocol.

 

 

Features

  • Promotes reliable amplification on most DNA templates

  • Tolerance toward primer annealing temperature

  • 10X buffer

 

Available in 4 options: Picture: “Ampliqon 10x Combination Buffer, 15 mM”.

  • 15 mM MgCl2

  • Mg2+ free

  • Tween free

  • Mg2+ & Tween free
