Fig. 5 — Degradation of DNA in NovaBlue cells following exposure to HOCl. Conditions: E. coli suspended at the indicated cell densities in 50 mM phosphate, pH 7.4, incubated 15 min at ambient temperature, then oxidant quenched with excess Na₂S₂O₃, and the DNA isolated and run on 0.8% agarose. Panel a: 2.4×10⁸ plasmid-free cells/mL, for which LD₉₀ ~38 µM (color photograph) ; panel b: 5×10⁷ pETBlue transformed cells/mL, for which LD₉₀ ~8 µM.
