Hello, I have used in the past P2069, which needs the equilibration buffer for pH8. Does P3803 also need the same equilibration buffer B5658-1EA? Thank you!

I received two bottles. One for the phenol and one for the buffer. Do I need to add the phenol to the buffer? or the buffer already contains the phenol?
1 answer-
Yes, the equilibration buffer is to be added before use, according to the following instructions:
Add the entire contents of the small bottle of Equilibration Buffer to the large bottle of Phenol:Chloroform:Isoamyl Alcohol reagent.
Mix gently and allow the phases to separate before use, typically 2–4 hours.
This will adjust the pH of the phenol phase from pH 6.7±0.2 to 8.0±0.2.Please see the link below to review the product datasheet for additional information:

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 answer-
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.
