RE: [Histonet] Efficiency of p o and m xylenes in dewaxing

From:"Smith, Allen"

I have never tried the pure isomers myself, but three of my professors told
me that all 3 or any mixture thereof were equally effective. (They probably
just heard it from their professors.) The mixed xylenes (which also contain
some ethylbenzene) are a little cheaper than m-xylene and much cheaper than
the other pure isomers.

Hi all,

Would anyone have any information on the relative efficiencies of para, meta
and ortho xylenes in dewaxing paraffin sections for nucleic acid extraction.

Does it matter?
