I realize this is going to sound like a shameless plug, but I did it
in one of my papers, and you could get the reference I used from it.
Basically you soak the gel slice in an excess volume of 20 mg/ml
CNBr in 70% formic acid, overnight at room temp in the dark; then
collect the liquid and lyophilize it; dissolve the dried protein
in water and lyophilize again (to get rid of trace CNBr and Formic Acid).
The paper is Thatcher,TH and Gorovsky, MA.
Experimental Cell Research. 209(2):261-70, 1993 Dec.
