Does anyone have any practical experience using a substitute for chloroform
during nucleic acid extractions?
We routinely extract nucl acids using GiTC and pheonl/chloroform-2%
The way we have things set up in our lab we HAVE to do the ext'ns in
polypropylene 1.5 mL Eppendorf
microtubes (for speed, efficiency and through-put).
Too many tubes for our liking leak during the chloroform ext'ns.
Chloroform has NO surface tension, thus leaks easily in ANY brand of tube
(we've tested them all [dozens],
Costar, Eppendorf, etc, etc).
I'm going to try a few different poly-chloro-n-butanol instead ... and will
post the results. Hopefully it will be
hydrophobic enough to denature proteins sufficiently as well as be dense
enough to bring down the phenol
with it in the microfuge.
