Figure 4. — AFM images of H.pylori HP-NAP in the presence of short DNA fragments. (A) HP-NAP incubated with 27 bp dsDNA at pH 6.5. (B) HP-NAP incubated with 27 bp dsDNA at pH 7.5. (C) HP-NAP incubated with 27 nt ssDNA at pH 6.5. The large white globular features in panels A and C represent HP-NAP–DNA aggregates in which DNA is not visible because of its small size. The white dots in panel B represent single HP-NAP dodecamers. The image scan size is 2 μm.
