Plasmid stability

[Ian A. York]

This may be too broad a question, but what the heck.  How stably are 
plasmids maintained in S cervisiae?  That is, if you stop selective 
pressure, and assuming that the plasmid isn't expressing something toxic, 
what kind of half-life will it show?  Will most of the plasmid be lost 
after 6 hours in culture?  24 hours?  A week?  Or is it unpredicatable, 
or does it depend on other conditions?  I'm specifically thinking of 2 
micron plasmids, but any information would be helpful.
