I'm working on a two-hybrid screen and I've
obtained 109 "positives?" clones that grow
easily on SD/-TDO medium + x-alpha-gal.
I'm working with S.cerevisiae AH109 yeast (BD
Matchmaker Library Construction and Screening Kits).
My problem is that PCR, sequencing (there's
nothing, it don't start) and even enzymatic restriction don't work...
I've already tried many miniprep protocols before
PCR reaction: PCR don't work... even colonies
screening by PCR don't work... PCR made from
colonies or miniprep (from bacteria, after
transformation either by electroporation or thermic choc) don't work too...
PCR on control plasmid that never goes into yeast work fine.
Could you please help me??
Is threre a contminant due to that yeast... Is
there modificatin of the DNA...???
What could be the problem??
Thank you very much indeed,
Have a nice day;
