General description

A tris-equilibrated phenol solution is a clear liquid capped with a layer of Tris buffer. Phenol solutions can be used for a wide variety of molecular biology applications. Organic compounds like phenols have an aromatic carbocyclic ring with a hydroxyl group attached directly to it. The common name for monohydroxybenzene is phenol.[1]

Application

Phenol solution has been used:

  • as a component of the digestion reaction mix to prepare RNase-free plasmids for in vitro translation in a rabbit reticulocyte lysate
  • for extraction of DNA from Arabidopsis thaliana Rosette leaves
  • in the extraction of DNA from blood on preservation paper by standard phenol-chloroform protocol
  • as a component of extraction buffer to extract RNA from fruit pulp
  • for the extraction of protein from roots[2]
  • for the isolation of fecal DNA[3]
  • for the extraction of caged RNA[4]

Biochem/physiol Actions

The phenol-chloroform extraction method is widely employed to extract nucleic acids. Even though phenol does not completely inhibit RNase activity, its unique characteristic makes it beneficial for the isolation of nucleic acids when used in combination with chloroform and alcohol.[5]

Components

  • 1 bottle Tris-equilabrated Phenol (product number P4557)
  • Equilibration Buffer (product B5658)

Questions

1–6 of 6 Questions  
  1. What is the export packaging? Is it in thermocol/Foam packaging? Can you share the packaging Image.

    1 answer
    1. Both package sizes are bottles that are sealed in a polyamide bag. This bag is placed, with additional absorbent material and padding, in a metal can with a pull tap. The final packaged item is placed in the shipping box that is most compatible with the order. This product is shipped at ambient temperature.

  2. I see that there are two layers in the bottle Phenol solution, Product P4557. Which layer do I use?

    1 answer
    1. The top phase is Tris buffer, so use the lower/bottom phase.

      Helpful?

  3. What do I do to equilibrate the Phenol solution, Product P4557, to around pH 8?

    1 answer
    1. This phenol solution (Product No. P4557) includes a separate bottle of equilibration buffer (Product No. B5658) to adjust the phenol phase to pH 7.9±0.2. After addition of the buffer to the phenol, it may take about 6 hours (mixture can be kept at 2-8 °C) until the bottom phase (phenol) becomes clear. Some of the haziness in the phenol phase may be due to some air bubbles caused by mixing by inversion. There could be a hazy interface between the phenol and aqueous phase which remains after the separation.  The entire contents of the bottle of the buffer should be added to the phenol. If buffering less than the complete bottle, use at a ratio of 6.5 mL buffer to 100 mL phenol. For 10 mL of phenol, use 650 μL of buffer. For 1 mL of phenol, use 65 μL of buffer.

  5. What is the final pH of Phenol solution, Product P4557, after adding the buffer?

    1 answer
    1. The pH is typically 8.0; the specifications state a range of 7.7-8.1.

      Helpful?

  6. What is the molarity of Phenol solution, Product P4557?

    1 answer
    1. The Molarity is ~10.6.  The density of the phenol is 1.05g/ml, and the molecular weight is 94.11.
