Chromatography results from purified K5 capsular polysaccharide, showing the two main fractions of lipopolysaccharide molecular weights (i and ii indicate molar masses of 47 and 27 kDa, respectively, according to the different injected volumes). These scattering signals were detected using different detectors: a Wyatt Helios 8-angle light-scattering detector (blue), an Optilab rEX refractometer (green), and a QELS dynamic light-scattering detector (cyan). The molar mass (Mw) was interpreted using Zimm plot analysis70,71 (magenta).
