Please see the link below to review the product datasheet. Note that the prepration instructions require the addition of the entire vial (6.5 mL) of equilabration buffer to the contents of the product. Aliquot immediately after the gentle mixing step. During the 2 - 4 hour incubation period the mixure will phase separate. At this point the aliquots may be stored for long term use according to the instructions.

애플리케이션
For applications requiring a higher pH, such as the isolation of large intact genomic DNA, addition of the Equilibration Buffer is recommended.
포장
Supplied with P3803 and a separate bottle of equilibration buffer to adjust the phenol phase to pH 8.0 ± 0.2.
적합성
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.
제조 메모
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.
기타 정보
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)

After equilibrating with the supplied Tris buffer, can I aliquot this for use, if so, should I just top each aliquot with additional Tris pH 8?

I ordered Product P2069, Phenol:Chloroform:Isoamyl Alcohol 25:24:1; I got one bottle of the Phenol:Chloroform:Isoamyl Alcohol and one bottle of B5658, Equilibration buffer. When and how am I supposed to use the B5658?
1 답변-
B5658 is a Tris buffer that is used to raise the pH of the phenol:chloroform:isoamyl alcohol mixture, to make it suitable for isolation of genomic DNA. The contents of the two bottles need to be well mixed. Then allow the mixture to separate; this may take 2-4 hours. This procedure should raise the pH of the phenol phase from 6.7 to about 8.0. Only one "treatment" is needed. This solution should be stable for up to 12 months.

There is an Equilibration Buffer (Product B5658) that is included with Product P2069, Phenol:Chloroform:Isoamyl Alcohol 25:24:1. Is B5658 also available separately?
1 답변-
No, it is only available as part of P2069.

I see that you list two equilibrated Phenol:Chloroform:Isoamyl alcohol products. When should I use Product P3803, and when should I use Product P2069?
1 답변-
In short, P3803 is for RNA work, and P2069 is for DNA work. Product P2069 consists of one bottle of Product P3803 and one bottle of Product B5658. The B5658 is added to the P3803 to raise the pH of the organic phase from 6.7 to 8.0; pH 8.0 is not suitable for RNA work, because RNA can degrade at the higher pH.
