Hi netters,
I have been trying to stain nuclei of S. pombe with Hoechst 33258
stain. I get great staining of the nuclei, but I also see very
intense  staining of the septa. Can someone please shed some light on
why a DNA-specific dye would stain the septa? Is this normal for
pombe? I have tried to use DapI, but the staining is not as
intense and not as consistent as hoechst. Any help would be
greatly appreciated (please respond to my e-mail address)
