freezing medium - how long can u store it? (Sep/09/2005 )

I wonder how long can you keep freezing medium at 4 degrees?

two month is ok. I've never try to keep it more.

I keep it for quite some time. If there is no contamination it should be ok. I prefer to store it -20 deg C though in 5-10 ml aliquots and always my cells are fine.
