After a complex carbohydrate mixture was obtained by solid-phase synthesis, the desired oligosaccharide containing a free carboxyl group derived from CPB was attached to an amino resin. The loaded resin was readily separated from side products by filtration and finally treated with acid to release the pure oligosaccharide product.
