Subcellular fractionation

We are studying the cellular expression of an enzyme which can exist both
in the Golgi and at the level of the cell membrane. In vivo, subcellular
fractionation is relatively straightforward using a differential gradient

However, I have not come accross a parallel method for separating the
plasma membranes and Golgi fractions from a cultured cell monolayer. This
is a particular problem when the small amount of starting material is taken
into consideration. Has anybody elso come accross this problem, or how it
may be addressed?
