Ordered collections of barcoded deletion mutants can be screened rapidly in mixed cultures to uncover resistance and sensitivity phenotypes associated with the loss of a gene. As such, they are invaluable tools for assigning gene function in the post-genomic era. In this protocol, we describe methodologies for creating and employing barcoded deletion mutants in competitive screens as well as how to analyze the ensuing results.
