dirty RNA prep

[cfb7 at psu.edu]

Hi,
I purified total RNA from mouse liver and spleen and while the spleen
RNA is clean and usable, the liver RNA is filthy.  It has a greenish
-yellow tint and a 260/280 ratio of 1.02.  My suspicion is that the
contaminating stuff is bile salts, but I don't know how to remove them.
 Phenol:chloroform extraction didn't help.  Any hints?  Thanks,
Christie
