High-Control(tm) BL21(DE3) (Lucigen) F - ompT gal dcm hsdS B (r B-m B-) (DE3)/Mini-F lacI q1 (Gent r) The HI-Control BL21(DE3) cells contain a single-copy BAC plasmid harboring a specially engineered version of the lacI q1 repressor allele. The lacI q1 allele expresses ~170-fold more lac repressor protein than the wild-type lacI gene.

We utilized the expression of the N-terminal His-tagged kinases in BL21 (DE3) E. coli strain for baseline comparison with four different expression improvement techniques: the addition of external folding chaperones and using the specialized strains: Rosetta, BL21 (DE3) pLysS, and Arctic Express.

In this work, four bacterial strains, BL21 (DE3), BL21 (DE3) pLysS, Rosetta, and Arctic Express, were chosen for parallel expression trials along with BL21 (DE3) complemented with folding chaperones DnaJ/K and GroEL/ES to compare their performance in producing soluble and active human kinases.
