摘要： An object of the present invention is to provide a glucosamine-containing glucan, a modified product and a conjugate thereof. The glucosamine-containing glucan of the present invention is a glucosamine-containing glucan wherein the glucan has a plurality of non-reducing ends and at least one glucosamine residue is bound via an ±-1,4-bond to each of two or more non-reducing ends of the branched ±-1,4-glucan, but no glucosamine residue is present at a position other than the non-reducing ends of the branched ±-1,4-glucan, wherein the degree of polymerization of the glucan is 15 or more and 4 x 10 5 or less. Theglucosamine-containingglucan of the present invention can be provided by allowing an ±-glucan phosphorylase to act on an aqueous solution comprising a branched ±-1,4-glucan and glucosamine-1-phosphate.
