General description

Sigma’s Yeast Transformation Kit contains all necessary reagents and controls for efficient transformation of yeast by the lithium acetate method.


Transformation with a plasmid complementing the mutated gene enables the transformant to grow on medium lacking the required component. Yeast cells are made competent for transformation by incubation in a buffered lithium acetate solution. Transformation is then carried out by incubating the cells together with transforming DNA and carrier DNA in a solution containing polyethylene glycol (PEG).
