Phloxine B

Dear Wojtek et al.,
We use Phloxine B to identify haploid colonies in S. pombe.  We simply add 15
mg/l to our standard rich medium.  The diploid colonies have more dead cells
in them than do the haploid colonies, thus three or four days after streaking
for single colonies, the difference is dramatic.  However, upon further
incubation the difference becomes less distinct.

Dear netters,

Has anyone used phloxine B for cell viability staining?
I will appreciate any protocols/suggestions/comments.
