Species:Escherichia coli
Group:K12
Strain designation:DH5αF(λ)
Accession number: LMBP 2846
Depositor: Prof. Dr E. Remaut1 2
1 Department for Molecular Biomedical Research, VIB, Ghent, Belgium
2 Department of Biomedical Molecular Biology, Ghent University, Ghent, Belgium
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-Lennox
Selection marker: /
Temperature: 28°C (Note: 37°C is also possible but phage lambda remains more stably integrated when grown at 28°C)
Genotype: F+ Δ(argF-lac)169 φ80dlacZ58(M15) ΔphoA8 glnX44(AS) λ+ deoR481 rfbC1 gyrA96 recA1 endA1 thiE1 hsdR17
Phenotype: NalR rK- mK+
Properties: Useful strain for Lacα complementation. This strain does not contain the lacIq gene and therefore repression on the lac promoter, present on high-copy plasmids, is incomplete.
Further information: This strain contains the F factor of NK3 and therefore can be used for infection with M13 or fd phages and derivatives. In addition the strain is lysogenic for wild-type phage λ.
