The Frequently Used GAL4 Driver table is intended to reflect how GAL4 drivers are used as experimental tools. We are enhancin this table with representative images of GAL4 driver expression patterns. We’d like to know if you’re using a GAL4 driver in a tissue/stage not recorded in this table, or if you’d like to contribute an image: please specify which GAL4 driver, using symbols from the Allele column. You can also suggest a GAL4 driver you think should be included. We’d like to hear any comments or suggestions you have to improve the Frequently Used GAL4 Drivers table.
