and that this oxidized phenol is damaging to dna and is thus unadvisable to use for dna (or rna) extraction.
Andy concrete data on shelf life (in a dark bottle, under tris, at 4oC)?
Folks say the color change is a reliable indicator of oxidation.
As for the color, people say pink is bad, but also "darker" or "reddish" yellow.
Anybody have any better input on these shades of yellow?
because isn't the new stuff a bit yellow too?
thanks in advance for responding to my (potentially silly) questions?
