*Constitutive expression of pClpXP from native promoter in a pBR322 vector backbone in LB at 37 °C

†Cells were harvested at OD₆₀₀=0.6, immobilized on 1 % agarose pads, and measurements determined using ObjectJ as described. Min. and Max., minimum and maximum cell lengths in the population.

‡n, total number of cells measured.
