Default Glycerol stocks from cultures in 2xYPAD (Anna Heidenblut)



Hi, Anna,

I truly don't see why it would be a problem. Actually, those cultures will
be growing very good and the cells will be quite robust. What I'd do is to
take the cells that you need for the transformation and place the rest in
the incubator while you are transforming, and, by the time you finish the
transformation, your cells will be probably nicely saturated and ready to
freeze (of course, with glycerol).

Hi,
I would like to determine the succinic semialdehyde level from heat
stressed yeast cells by enzymatic assay, could I simply boil the cells
to prepare the crude cell extract? How is the stability of SSA?


Best regards
Juxiang Cao

Dear all,

another elementary question:
Can it cause any problems when I prepare glycerol stocks from cultures
that were grown in double strength YPAD (YPD with additional adenin
added)? I use this 2xYPAD to grow pre-cultures for yeast transformation
and it would be very convenient to prepare glycerol stocks from the
pre-cultures immediately rather than setting up a separate culture in
YPD just for the preparation of glycerol stocks.

Any comments on that question are highly appreciated.

Anna

Does anyone have or know of a S. pombe genomic library on a
ura4+-containing plasmid?
