Southern blot assay. Purified genomic DNA of H. influenzae was restricted with EcoRI and hybridized with 200 bp probes corresponding to ureA, ureC, ureH and kanamycin cassette (kan) as noted at the bottom of each panel. Lanes a) wild type strain 11P6H; lanes b) urease operon mutant 11P6Hure-. Molecular size markers are noted on the left in kilobases.
