phloxin B: follow-up

[Belhumeur Pierre]

Fellow netters,

Here's the latest (and only!) answer I received: that speaks for itself. 
I wish to thank Mike Moser for explaining how phloxin B works. I must say 
that I tried the pombe concentration (2.5 mg per L, sterilizing the 0.5% 
stock solution by filtration) and it seems to work too: as you'll see 
below, Vickie uses this stain at 20 mg per L but it is autoclaved with 
the medium. Any concentration will do!!

Again, thanks everybody

Subject: Phloxine B Screening

Dear Dr. Belhumeur;
        I am responding to your request for  information regarding phloxine
B .  We have used phloxine B to screen for stationary phase mutations in S.
cerevisiae.  Phloxine B  is added directly to the medium at 20 mg/l, which
is autoclaved as usual.  For more information, see Cannon et al., Genetics
113:247-264 (1986).  Good luck!
                                Sincerely,
                                Vickie Peck
