Figure 5: LPS analysis in the presence of divalent cations.

(a) Small-angle neutron scattering (SANS) analysis of LPS (10 mg/ml) and OligoG CF-5/20 (20 mg/ml) in the presence of 5 or 10 mM Ca²⁺ in 0.01 or 0.10 M NaCl at pH 7. (b) Circular dichroism spectra of 20 mg/ml OligoG CF-5/20 in the presence of 10 mg/ml LPS in 0.10 M NaCl were recorded in the presence and absence of 5 mM Ca²⁺ at pH 5 and pH 7 at 37 °C; buffer spectra including LPS were subtracted.
