Comments: Genotype: λDE3 Δtig100 Δ(araD–araB)567 ΔlacZ4787(::rrnB-3) lacIP-4000(lacIQ) rph-1 Δ(rhaD–rhaB)568 hsdR514 KTD101(DE3) is a λDE3 derivative of the trigger factor deficient (Δtig) strain KTD101 from Puertas et al 2010 Protein Expression and Purification 74: 122–128, PMID 20600941. Puertas et al 2010 showed that deletion of trigger factor in the parent strain KTD101 increased the level of secreted recombinantly expressed protein. This strain may also improve the level of protein expression in the periplasm and in the outer membrane. This derivative strain KTD101(DE3) now allows expression that is based on the widely-used T7 promoter. The parent strain KTD101 was provided by François Baneyx at the University of Washington. DE3 lysogenization is apparent from positive expression that was obtained for the BBA57 protein upon expression from the T7 promoter plasmid pBBA57-TEV-His12, as was shown in Figure S5C, lane 7, of Robertson et al, Sci Rep. 2019 Nov 26;9(1):17606. doi: 10.1038/s41598-019-53830-x.
