Microsome prep from cultured cells: methods?

My lab is currently isolating microsomes from cultured cells, 
specifically an enterocyte line, but the procedure we use has been used 
for HepG2 cells in the past as well. Unfortunately I do not have the 
procedure here at home this evening. I will bring it home tomorrow night 
and post it if I can. Basically, you just harvest a large number of cells 
(by scraping) and put them through several cycles of freeze-thaw (liquid 
N2/37oC). After that it's just a matter of going through a standard 
microsome preparation by differential sedimentation.
