Representative AFM images of protein-DNA complexes formed between mIHF-80 and negatively supercoiled plasmid DNA.

<p>(A) Plasmid DNA in the absence of mIHF-80. (B)–(I): mIHF-80-pPROEX-HTc complexes with increasing mIHF-80 dimers per 10 base pair of DNA as follows; (B) 1, (C) 2, (D&E) 4, (F & G) 8. The scale of all images in A to G is (3 µm×3 µm). (H) & (I): Rigid nucleoprotein filaments identified in (F) and (G) above are shown at a slightly magnified scale of (1 µm×1 µm). The protein complexes are marked by arrows.
