RNA sequencing and analysis E. coli BL21(DE3) cells (NEB: C2527H), which lack endogenous copies of IS621 elements, were transformed with plasmids encoding either the RE–LE junction or the LE–recombinase–RE region of the IS621 element. The cells were plated on LB (lysogeny broth) agar with kanamycin and grown overnight at 37 °C. Colonies were scraped from the
