Hi,
I prepared total RNA from plants (A. t.) grown on soil using Trizol
and have large amounts of contaminations of substances stated in a
manual
for TRIFAST (from peqlab, similar to Trizol) could well be proteoglycans

and polysaccarides copurifying with RNA and having similar UV
absorption.
They say in the manual, that a further purification with Optipure
(Peqlab
as well) eliminates these problems. Does anybody have experiences with
these kind of problems who can provide help (experience with Optipure or

similar stuff, home-made protocols etc...).

thanks in advance,

Harald F. Sigmund
