Synthetic Genetic Array (SGA)


Synthetic Genetic Array (SGA) is a high throughput approach allowing the systematic generation of double mutants. Using a query strain, carrying a mutation of interest that is then crossed with a library of mutants, one can obtain double mutants and score for synthetic interactions. Such screens have been used extensively over the years to decipher the complexities of genetic networks and pathways in yeast. A fully equipped laboratory dedicated to SGA technique has been established at Institut Curie in 2012 and is available to all interested yeast and non-yeast research groups.
