Fig. 2From: Identification of stress-responsive transcription factors with protein-bound Escherichia coli genomic DNA librariesAnalysis of LexA-containing clones in response to mitomycin C treatment. From protein-bound genomic DNA fragment libraries, five clones containing LexA binding sequences were identified through sequencing and TFBS motif search. These clones were selected and treated with 0, 0.2 and 0.5 μM mitomycin C for 2 (a), 4 (b), and 16 h (c) respectively. Cells were collected for luciferase analysisBack to article page
