Description
This E. coli strain can be used to propagate plasmids with R6K conditional replication origin (
BBa_J61001,
BBa_K300998), such as
BBa_K300000 integrative base vector after the excision of its insert (
BBa_I52002).
BW23474 propagates R6K origin at a copy number comparable to medium copy plasmids (~15 plasmids per cell) [1].
Genotype:
F-, Δ(araD-araB)567, ΔlacZ4787(::rrnB-3), Δ(phoB-phoR)580, λ-, galU95, ΔuidA3::pir+, recA1, endA9(del-ins)::FRT, rph-1, Δ(rhaD-rhaB)568, hsdR514
Notes
This is not the only strain able to propagate R6K at medium copy, but it has been mentioned in several papers and it is easily retrievable from the CGSC.
