Application

For applications requiring a higher pH, such as the isolation of large intact genomic DNA, addition of the Equilibration Buffer is recommended.
Phenol:Chloroform:Isoamyl Alcohol has been used in the preparation of RNA for the study of total RNA isolation from myocardial biopsies. It has been also used to extract DNA during Human Androgen Receptor (HUMARA) Clonality Assay.

Packaging

Supplied with P3803 and a separate bottle of equilibration buffer to adjust the phenol phase to pH 8.0 ± 0.2.

Suitability

This lot of phenol:chloroform:isoamyl alcohol 25:24:1 was use tested by extracting a crude preparation of pBR322 DNA preparation from E. coli. Based on evaluation by agarose gel electrophoresis the extracted DNA was not degraded or reduced in concentration. The same procedure was applied to purified pBR322 DNA and lambda Hind III digest DNA. Based on electrophoretic evaluation the purified preparations were not detectably degraded or reduced in concentration.

Preparation Note

Add the entire contents of the small bottle of Equilibration Buffer to the large bottle of Phenol:Chloroform:Isoamyl Alcohol. Mix gently and allow the phases to separate before use, approximately 2-4 hours. This will adjust the pH of the Phenol solution from pH 6.7 ± 0.2 to 8.0 ± 0.2.

Other Notes

After the addition of Equilibration Buffer, the product is stable for 6 months vs. 2 years without added buffer. Storage at -20 °C protected from light extends the shelf life to greater than 1 year after the addition of Equilibration Buffer.

The endocannabinoid (eCB) system possesses neuromodulatory functions by influencing the release of various neurotransmitters, including γ-aminobutyric acid (GABA) and glutamate. A functional interaction between eCBs and the serotonergic system has already been suggested. Previously, we showed that cannabinoid type-1 (CB1)
