Figure 4From: Physicochemical characterization of the endotoxins from Coxiella burnetii strain Priscilla in relation to their bioactivities0° and 90° polarized infrared spectra of lipid A from C. burnetii strain Priscilla in the wavenumber range 1500 to 900 cm-1. The vibrational bands at 1171 and 1040 cm-1 correspond to diglucosamine ring vibrations.Back to article page
