Abstract
An oligosaccharide having an affinity for fibroblast growth factor, which is composed of 8 to 18 monosaccharide residues, wherein a principal disaccharide unit comprising L-iduronic acid 2-sulfate and N-sulfo-D-glucosamine and a process for producing the oligosaccharide comprising digesting heparan sulfate.
Claims8
An oligosaccharide with affinity for fibroblast growth factor (FGF) and no reactivity with antithrombin III and heparin cofactor II, and which enhances dispersion of fibroblast growth factor in an extracellular matrix, wherein said oligosaccharide has 16 to 18 monosaccharide residues, and contains at least one disaccharide unit composed of L-iduronic acid 2-sulfate and N-sulfo-D-glucosamine.
An oligosaccharide with affinity for fibroblast growth factor (FGF) and no reactivity with antithrombin III and heparin cofactor II, and which enhances dispersion of fibroblast growth factor in an extracellular matrix, wherein said oligosaccharide has 16 to 18 monosaccharide residues, and contains at least one disaccharide unit composed of L-iduronic acid 2-sulfate and N-sulfo-D-glucosamine and the molar ratio of said disaccharide unit and a disaccharide unit composed of L-iduronic acid 2-sulfate and N-sulfo-D-glucosamine 6-sulfate is 3:1.
An oligosaccharide with affinity for fibroblast growth factor (FGF) and no reactivity with antithrombin III and heparin cofactor II, and which enhances dispersion of fibroblast growth factor in an extracellular matrix, wherein said oligosaccharide is a degradation product of heparan sulfate using heparitinase I, has 16 to 18 monosaccharide residues, and contains at least one disaccharide unit composed of L-iduronic acid 2-sulfate and N-sulfo-D-glucosamine.
