Dear Andrew,

Although you don't say what is your problem, I would recommend to
use the following lysis buffer:

50 mM Tris-HCl (pH 8.0), 100 mM NaCl, 5 mM MgCl2, 0.5%(v/v) Nonidet P-40
and 1 mM DTT. Add protease, RNase inhibitor(s) if necessary. Note that 
the concentration of Nonidet can be increased/decreased depending
on your needs. This coctail guarantees 100% lysis for most monolayers.
I have used it for RNA/protein fractionations.

Hope this helps,

Mart
