Dear Rudolf,

when I did western on samples from patients, I lysed the cells directly in
9M Urea 150 mM b-mercaptoethanol. Another option (eg when you have to do
the subcellular separation) is to use an inhibitor-cocktail (eg the one by
Boehringer Mannheim). However, I found that degradation is very often
dependent on the way the samples had been handled by the medics before I
actually got hold of them.
Hope this helps,
