FACE results for the ANTS-labeled standard oligosaccharides and definition of the RMI. The RMI of monomeric glucose and the oligosaccharides derived from dextran were assigned unit values based on the number of hexose residues, i.e., glucose RMI 1.00, maltose RMI 2.00, etc. Every other migration position is expressed as a fraction of the linear distance between two adjacent reference points. Migration positions between the ANTS front, RMI 0.00, and glucose, RMI 1.00, were calculated in the same manner. The RMI of monomeric glucose (1.00), mannose (1.18), galactose (1.18), and arabinose (0.75) and of the α-1,4-oligoglucosides (⋄) and maltooligosaccharide (⌖) are indicated.
