	Things are very different in vivo.  Even if your buffer manages to
duplicate the precise ionic conditions in the cell, the protective effects
of all that glutathione, and the high total protein concentration, there
are still the "molecular chaperones" to consider--the hsp70s and all their
little friends.  They're always there, presumably looking out for
partially denatured proteins, and binding them and helping them back to
their minimal energy conformation when they find them.
