Acid Phenol/chloroform

I got a kit from Ambion to do some RACE, this kit requires acid
phenol/chloroform but doesn't tell me what the composition of this is.
I called Ambion and they didn't know. I couldn't find a recipe in
Maniatis either.

I have a brand new bottle of phenol ph 6.7. What do I need to add to
make "acid phenol/chloroform"? Thanks.

Water-saturated phenol is "acid phenol (phenol has a weakly ionizable
hydrogen)." What you have is likely buffered.

Start with solid phenol crystals, and saturate it with good water (you
might need to do it a couple of times). Standard safety disclaimers
apply (wear gloves and eye and body protection, etc.).

Since phenol is one of the really nasty chemicals in the molecular
biology lab, I would rather buy the ready-to-use substance.
