| New search | Print data sheet |
| Species: | Escherichia coli |
| Group: | K12 |
| Strain designation: | W3110 Crow |
| Accession number: | LMBP 13409 |
| Depositor: | This host strain was deposited by Prof. Dr B. Wren1. It was constructed by Dr E. Kay1. 1 Department of Infection Biology, London School of Hygiene and Tropical Medicine, London, UK |
| 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). |
| Other culture collection numbers: | - |
| Medium: | LB-Lennox |
| Selection marker: | / |
| Temperature: | 37°C |
| Genotype: | F- λ- IN(rrnD-rrnE)1 rph-1 ΔlpxM ΔwaaL (Source: Kay et al. (2022)) |
| Phenotype: | - |
| Properties: | This host strain is a derivative of the Raptor strain and can be used for bioengineering where purified products with reduced endotoxicity are desirable. The O-antigen ligase has also been removed so that recombinant glycans are not removed from Und-P and attached to surface lipid. waaL was removed in the Raptor strain using CRISPR technology. |
| Further information: | This strain is part of a versatile suite of glycoengineering strains for various downstream applications, such as glycoconjugate vaccine production. |
