YPD Plus

The outgrowth step in yeast transformation protocols is often critical for increasing overall yeast transformation efficiencies. Following treatment of yeast with lithium acetate and polyethylene glycol solutions, it is often necessary to add medium to allow for a period of outgrowth, which normally results in increased cell survival. This is useful when attempting to maximize transformation efficiencies for library screening or transforming yeast with multiple plasmids. YPD Plus is a special formulation of conventional YPD outgrowth medium that increases yeast transformation efficiencies by >...
