Abstract
Anti-angiogenic protein composition can be prepared simply and efficiently by contacting cartilage particles containing the protein together with an electrolyte solution and an oligosaccharide bearing a minimum number of anionic substituents per sugar unit, to extract the anti-angiogenic protein from the cartilage particles and to form a complex of the oligosaccharide and the protein. The resultant anti-angiogenic complex can be used for therapeutic treatment of various angiogenic and related diseases.
