Clean RNA from dirty roots...

You might want to try Ambion 'plant  RNA isolation aid' solution (cat # 9690).
You can add the solution to the lysis buffer in the Ambion RNAqueous kit or to
the lysis buffer in the Qiagen RNeasy kit. It works great!.

Hello All,

Judging by what I've found in the archives of this list, this subject
might be an old one but I still haven't found any successful methods.

My problem is that I have to work with soil grown plants which produce a
lot of mucilage, which in turn binds a lot of soil.  Scrubbing of the
roots is not an option in this case and, having tried various kits, the
result is either a pellet with a large amount of brown gunge with it or
no RNA recovered at all (I suspect because it was bound to the brown
gunge that some methods get rid of).

So, my question is, does anybody have a reliable method for getting good
quality RNA out of dirty plant roots to yield a nice, clean prep?

All suggestions welcomed.

Thanks in advance,
