glycerol to avoid protein precipitation?...

[Arioch]

hey all,
	...had heard seomwhere that adding glycerol to purified protein
and then freezing them keeps the breakdown at a minimum and prevents 
protein precipitation (after freeze-thawing from the -20 degrees C).
has anybody tried this??  i wouold really appreciate any help on
this...thanks...
