Species:Escherichia coli
Strain designation:DH5αpir116 variant
Accession number: LMBP 7961
Depositor: Prof. Dr M. Herrington1
1 Biology Dept, Concordia University, Montreal, Canada
It was obtained from Dr G. Philips2
2 College of Veterinary Medicine, Dept of Microbiology, Iowa State University, Ames, Iowa, USA
Containment level: This strain has been assigned the containment level Class 1 following the European Directive 2009/41/EC on the contained use of genetically modified organisms, and its updates (see also the Belgian risk group classification).
Medium: LB-Miller
Selection marker: /
Temperature: 37°C
Genotype: endA1 hsdR17 glnV44 (= supE44) thi-1 recA1 gyrA96 relA1 Φ80dlacΔ(lacZ)M15 Δ(lacZYA-argF)U169 zdg-232::Tn10 uidA::pir116
Phenotype: TetS NalS
Properties: This is a host strain for R6Kγori plasmids. In pir116 strains, R6K-containing plasmids replicate like high-copy pUC plasmids.
Further information: Personal communications of Prof. Dr M. Herrington: The E. coli K12 DH5αpir116 variant appears to have lost the Tn10 and is consequently tetracycline sensitive.

BCCM/GeneCorner could not experimentally confirm the nalidixic acid resistance, conferred by gyrA96, nor the tetracycline resistance, conferred by Tn10.
