	Ira Mellman's group has succeeded in isolating endosomal organelles
using an electrophoresis technique.  I heard him speak in 1996, about the
time that Immunity 1996 Mar;4(3):229-239 came out, so you might want to
start with that reference.  I don't know whether this would suit your needs,
since you seem to want to use gradient centrifugation, but check it out.

	Good luck!
