G-418 selection

[Neil Bromberg 5-5785]

I am trying to find out how to use G-418 selection with electroporation for
yeast transformation.  Are cells selected directly on G-418 plates or is it 
added after a period of growth.  How many hours after plating?  I have tried
3 hours and 18 hours without much success.  Any suggestions will be greatly
appreciated.
