(a) ESI mass spectrum acquired in negative ion mode for an aqueous ammonium acetate solution (200 mM, pH 7 and 25 °C) of NoV VA387 P particle (3 μM) and a 20-component (10 μM each) carbohydrate library consisting of the oligosaccharides of GM1a, GM1b, GM2, GM3, GD1a, GD1b, GD2, GD3, GT1a, GT1c, GT2, GT3, Fuc-GM1, asialo GM1, asialo GM2, Gb3, and Gb4 as well as the H3, B3, and A3 oligosaccharides. (b) CID mass spectrum measured for the −61 charge state of the free and ligand-bound P particle.
