Just wonder if there is a good method to recover the yeast clones from a
The glycerol stocks were prepared 5 months ago, they are clones screened
by Yeast Two-Hybrid system, with yeast strain Y187 mated to PJ69-2A, and
then they were inoculated in QDO SD medium, when they grown up, glycerol
was added and quick freezed by liquid nitrogen and stored in -80C
At first, I thaw them and used a loop to streak them out on QDO plates,
they don't grow up, then I thaw them again and aliqioted 20ul and
spreaded on minus LT plates(less stringent I think), and just a few of
them grow up.
Anything I can do to improve the recovery?
Thanks for your help!!!!!
