Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 28 words
An oligosaccharide having an affinity for fibroblast growth factor, which is composed of 8- to 18-monosaccharide residues with a principal disaccharide unit comprising L-iduronic acid 2-sulfate and N-sulfo-D-glucosamine.
Claim 2
Dependent Claim 39 words
A process for producing an oligosaccharide having an affinity for fibroblast growth factor and composed of 8- to 18-monosaccharide residues with a principal disaccharide unit comprising L-iduronic acid 2-sulfate and N-sulfo-D-glucosamine, which comprises digesting heparan sulfate with Heparitinase I.
Claim 3
Dependent Claim 36 words
A process of claim 2, wherein the resulting digest is incubated together with an acidic or basic fibroblast growth factor-bound carrier in the presence of chondroitin sulfate, and subsequently desorbing the bound digest from said carrier.
Claim 4
Dependent Claim 26 words
A process of claim 2, wherein the heparan sulfate is derived from small intestines or aortas of cattle, swine or sheep and cockscombs of domestic fowls.
Claim 5
Dependent Claim 11 words
A process of claim 3, wherein said carrier is agarose gel.
Claim 6
Dependent Claim 68 words
A process for producing an oligosaccharide having an affinity for fibroblast growth factor and composed of 8- to 18-monosaccharide residues with a principal disaccharide unit comprising L-iduronic acid 2-sulfate and N-sulfo-D-glucosamine, which comprises incubating heparan sulfate together with an acidic or basic fibroblast growth factor-bound carrier, isolating a fraction of the heparan sulfate which binds to said carrier and digesting the isolated heparan sulfate fraction with Heparitinase I.
Claim 7
Dependent Claim 36 words
A process of claim 6, wherein the resulting digest is incubated together with an acidic or basic fibroblast growth factor-bound carrier in the presence of chondroitin sulfate, and subsequently desorbing the bound digest from said carrier.
Claim 8
Dependent Claim 34 words
A composition comprising two or more of oligosaccharides having an affinity for fibroblast growth factor, which is composed of 8- to 18-monosaccharide residues with a principal disaccharide unit comprising L-iduronic acid 2-sulfate and N-sulfo-D-glucosamine.
Claim 9
Dependent Claim 44 words
A pharmaceutical composition comprising fibroblast growth factor and at least one of oligosaccharides having an affinity for fibroblast growth factor, which is composed of 8- to 18-monosaccharide residues with a principal disaccharide unit comprising L-iduronic acid 2-sulfate and N-sulfo-D-glucosamine, and a pharmaceutically acceptable carrier.
Claim 10
Dependent Claim 15 words
Use of an oligosaccharide according to claim 1 for the manufacture of a pharmaceutical composition.
