A method for the separation of M- and G-chains of laminarans (reserve β-glucans of brown algae) is proposed. G-chains were converted to the corresponding pyridylamino derivatives by treatment with 2-aminopyridine and dimethylamine-borane complex followed by the separation of derivatized and underivatized chains by ion-exchange chromatography on Spheron S-1000.
