Dear yeast users
I am trying to integrate an integrative plasmid into Gap1 locus from
Saccharomyces cerevisiae. For that propose I am using a non buffered
minimal media (0.17% YNB w/o Nitrogen, 0.1% proline, 20mg/L uracile
and 2% glucose) containing 10mM of D-Histine. However, I am getting a
huge number of colonies in my control plate (yeast transformed
Does anyone have an idea how I can decrease this background ? Could
it be a pH problem, concentration of D-Histidine ?
Many thanks in advance for your recommendations.
