Description

Thermo Scientific Phire Plant Direct PCR Master Mix is designed to amplify DNA directly from plant samples.

Thermo Scientific Phire Plant Direct PCR Master Mix is designed to amplify DNA directly from plant samples. No DNA purification is required prior to PCR. The kit is based on Phire Hot Start II DNA Polymerase, a specially engineered enzyme with a DNA binding domain. The unique features of this DNA polymerase make it extremely robust and tolerant of many PCR inhibitors present in plant material like complex polysaccharides, polyphenols, and others.

Phire Plant Direct PCR Master Mix has been tested with leaves and seeds from a wide variety of plant species as well as fungi, bacteria, and yeast. The kit includes a complete set of optimized reagents and detailed protocols, making it an ideal choice for amplification of plant DNA.

Features

  • Direct PCR allows sample to be added directly to PCR reaction, reducing time-consuming and expensive DNA purification steps
  • Available Dilution & Storage protocol allows several PCR reactions from one sample
  • Specially engineered Phire Hot Start II DNA Polymerase for extremely short PCR protocol times
  • Master mix format with premixed gel loading dye minimizes risk of cross-contamination, reduces sample handling, and allows direct loading on gel

Applications

  • Genotyping
  • Transgene detection
  • Knockout analysis
  • Sequencing

Notes

  • Annealing temperature for Phire DNA Polymerases may differ significantly from that of Taq-based polymerases.

Frequently Asked Questions (FAQs)

What is your recommendation to take a sample from plant or animal tissue for Direct PCR?

In order to obtain best results from Direct PCR, it is important to use a very small amount of starting materials. The recommended size is 0.3-0.5 mm in diameter. We recommend using Tissue Puncher 0.3 mm (Cat. No. F-200S), which is a convenient tool for sampling and is suitable for both plant and animal tissues.

Why are Control primers provided in the Direct PCR Kits?

It is very important to include a control reaction in the Direct PCR to ensure that the PCR conditions are optimal for the specific tissue or plant material used. Control primers are universal primers that amplify a small fragment from a conserved genome region. If the reaction with control primers fails, the sample material may not be suitable for Direct PCR, or PCR conditions need optimization.
Can I use plant or tissue sample which is not on the list of the Direct PCR Master Mix and Kit tested samples?

You can test any plant or tissue sample. However, it is recommended to first optimize the reaction. When working with new sample materials, start with the Dilution & Storage protocol as it allows several PCR reactions to be performed from the same sample during optimization. It is recommended to perform a positive control with purified sample DNA to ensure that the PCR conditions are working. If the positive control with purified DNA fails, the PCR conditions should be optimized before continuing further.

Can you amplify the same sample materials with the Direct PCR Master Mixes as with Direct PCR Kits?

Yes, the Direct PCR Master Mixes are upgrades of the Direct PCR kits and thus are suitable for the same sample materials.
Do the Direct PCR Master Mixes and Kits come with tissue punchers?

No, tissue punchers are not provided. You can purchase 0.3 mm Tissue Punchers (Cat. No. F-200S), or cut the sample with a scalpel. Some scientists use 100 µL pipette tips to take a sample.
Do the Direct PCR Master Mixes work in Dilution & Storage protocol?

Yes, similar to the Direct PCR Kits, Direct PCR Master Mixes work in both Direct and Dilution & Storage protocols. Direct PCR from blood is performed with Direct protocol only.
Can I use frozen leaves with the Phire Plant Direct PCR Master Mix or Kit?

Yes, frozen (-20 degrees C and -70 degrees C), dried and fresh plant leaves can be used. We have succeeded in amplifying DNA directly from oak leaves stored at -20 degrees C for 10 years. However the highest amplification yields are achieved when using fresh samples.
What if I want to clone or sequence the PCR product from a Direct PCR kit? Can I use the kit with Phusion instead of Phire?

Direct PCR Kits and Master Mixes employ Phire Hot Start II DNA Polymerase or Phusion Hot Start II Polymerase (depending on the kit), that both possess the following activities: 5'-3' DNA polymerase activity and a weak 3'-5' exonuclease activity. When cloning fragments amplified with these DNA Polymerases, blunt end cloning is recommended. If TA cloning is required, it can be performed by adding A overhangs to the blunt PCR product. However, before adding the overhangs, it is very important to remove all the DNA polymerase by purifying the PCR product carefully. Any remaining Phusion or Phire DNA Polymerases will degrade the A overhangs, creating blunt ends again. All Direct PCR kits are compatible with sequencing techniques. The green dye present in the Direct Master Mix kits does not interfere with the sequencing reactions.
After performing Direct PCR, how should I store the PCR products amplified directly from the sample?

After PCR, it is recommended to centrifuge the PCR reactions at 1000 x g for 1-3 minutes to collect the supernatant for subsequent analysis. We recommend storing the supernatant at -20 degrees C
Are there any restrictions to the size of the amplicon in Direct PCR?

The optimal length for Direct PCR from liquid samples is up to 5 kb and from solid samples up to 1 kb. However, the maximum length depends on the sample type, sample size and the reaction volume. For example we have amplified a 7.5 kb fragment directly from human blood and tissue samples, and a 3 kb fragment from mouse ear and 5 kb fragment from plant leaves.
