Drug to kill actively growing yeast cells

An alternative method involves the enrichment for nongrowing cells due to
their resistance to heat killing.  This comes from a paper from the Pringle
lab (MGG 171:111-114).

Nystatin has been used for that. See R. Snow, Nature 211: 206 1966. 
There have been subsequent uses of the method, but I don't have references
handy. There are a couple of other methods described in McCusker and Haber, 
Genetics 119: 303 1988, using ethidium bromide or fluorouracil. EthBr 
apparently causes loss of mito DNA much more efficiently in growing cells 
than in arrested ones. So the rho+ survivors are enriched in mutants.

Hope this helps,
