MALDI-TOF with 2,5-DHB as matrix, determined the molecular mass of LMG. The gap with 162 Da between peaks represents a hexose unit in LMG. Sodiated ions ([ G l c n + N a ]+) appeared at D P = 6 to 15 with 1013.1, 1175.1, 1337.1, 1499.1, 1661.2, 1823.2, 1985.2, 2147.2, 2309.2, and 2471.3 Da, respectively.
