RNA from Spleen - Help!

[Alec Redwood]

I had trouble with spleen RNA with the brain working perfectly in mice. 
 I don't think I ever fixed it that well however it seemed to work 
better if I didn't use too much tissue at the start.  ie less spleen 
better result.  I also found alot of DNA contamination when I used too 
much spleen tissue.

: There isn't any RNAse contamination coming from equipment, tubes or

: isolated from the brain is fine.
