Figure 3From: Generation of comprehensive transposon insertion mutant library for the model archaeon, Haloferax volcanii, and its use for gene discoverySouthern analysis of transposon insertion mutants. Genomic DNA (2.5 μg) was digested with EcoRI + KpnI and probed with a transposon-specific probe. Purified TrpA-cat-Mu transposon (15.5 ng) and parental H295 DNA were used as positive and negative controls, respectively. Lanes 1 and 2 represent pigmentation mutants, lanes 3 and 4 auxotrophic mutants, and lanes 5 to 12 randomly selected uncharacterized mutants. Faint bands in lanes 11 and 12 are due to a smaller amount of DNA in these two samples.Back to article page
