ade2-101 suppressor?

My quick'n'dirty answer is different amounts of adenine in your different
media mixes.  The red color development is very senstive to this. (More
adenine=later or little color).

Looking more deeply, I wonder if there is something else going on?  Are
there other ochre-suppressible markers in your strain?  Is the suppressor
on a plasmid (as sectoring red on YEPD suggests?).  Tell me more!

Beth,

Only lys2-801 (?) and they are really lys minus.  No plasmids (that I know
of.

Thanks
