Intermolecular aggregation of intramolecularly condensed chains of HA deposited on freshly cleaved mica, observed in TMAFM height images. Bar = 250 nm. Z range 2.5–6 nm. (A) Moderate molecular weight bacterial HA deposited from 10 μg/mL solution in H2O. (B) Moderate molecular weight bacterial HA deposited from 10 μg/mL solution in H2O. (C) High molecular weight bacterial HA deposited from 5 μg/mL solution in 10 mM MgCl2. (D) High molecular weight rooster comb hylan A deposited from 500 μg/mL solution in 0.15 M NaCl.
