pGAL1+ w/XhoI sites

This is the GAL1 inducible promoter for use in Saccharomyces cerevisiae. It is induced by the presence of galactose and repressed by glucose. Raffinose is used as a neutral carbon source, with no effect on pGAL1. The promoter normally has an all-or-nothing response. To make it tunable, knock out the Gal2 gene.[http://www.jbc.org/cgi/content/abstract/M512317200v1]

Use these primers on a Kan resistance gene template: (the portion in bold binds to the template, the rest is homologous to the Gal2 gene on the yeast chromosome.)

Transform the product into yeast by standard procedure [http://www.natureprotocols.com/2007/01/31/highefficiency_yeast_transform.php], and select transformants with G418 YPD plates


To check for proper knockout, amplify the section of the chromosome where the insert should be. Use these primers:

Thanks to the lab of Christina Smolke for these primer sequences.
