FLUORESCENCE-BASED REPORTERS FOR MUTAGENESIS DETECTION IN E. COLI

摘要

Direct detection of mutagenesis in prokaryotes by reversion of an inactivating mutation (reversion mutation assay), producing a quantitative signal for in vivo mutagenesis, may greatly reduce the amount of test chemicals and labor involved in these assays. Further, transcriptional coupling of β-lactamase reversion and GFP, translational fusion between β-lactamase and GFP with stop codon in GFP, and a novel dual reporter to monitor continuous mutagenesis may be used in methods described herein.
