(A) Montage of fluorescence images of T4-DNA molecules inside 150 × 250 nm2 channels and in T-buffer. From left to right 2 × 10−4, 2 × 10−3 and 3.3 × 10−1 (condensed) μM Hfq. (B) T4-DNA inside 200 × 300 nm2 channels and in T-buffer with 2 × 10−4 (left) and 2 × 10−3 (right) μM Hfq. (C) T4-DNA inside 200 × 300 nm2 channels and in T-buffer with 30 mM NaCl. The Hfq concentrations are 2 × 10−4 (left) and 2 × 10−3 (right) μM. (D) Distribution in extension of a population of 30 molecules in T-buffer with 2 × 10−3μM Hfq. A Gaussian fit gives a mean extension R∥ = 10 ± 1 μm.
