cycloheximide selection in Y2H

Hello everybody!

Did anybody use the cycloheximide dominant selection marker in vector
pAS2-1 of the Matchmaker-2 kit? Does it work in the first generation or
several passes are needed to recover the colonies that lost this plasmid?

I have no experience with yeast, but I thought this was a good way to
start recovering putative interactor's plasmids, because in one step you
can test for the loose of B-gal activity of the positive colony, and to
get rid of the bait plasmid for the isolation and analysis of the clone.
Is this all correct or did I forget anything?

Thanks for your help,
