Patent number: 7521433Abstract: Disclosed are gene carriers utilizing ?-1,3-glucan and methods of preparing the same. The ?-1,3-glucan has at least one 1,6-glucopyranoside branch and is chemically modified through periodate oxidation and reductive amination so as to impart nucleic acid-binding functional groups (for example, cationic functional groups) to at least some of the 1,6-glucopyranoside branches thereof. Triple helix ?-1,3-glucan is dissolved in a polar organic solvent to form single-stranded ?-1,3-glucan. By replacing, in the presence of a nucleic acid, the polar organic solvent for the solution containing the chemically modified single-stranded ?-1,3-glucan by water, a complex (gene carrier) is formed in which the nucleic acid is bound to double-stranded ?-1,3-glucan.Type: GrantFiled: March 11, 2002Date of Patent: April 21, 2009Assignees: Japan Science and Technology Agency, Mitsui Sugar Co., Ltd., Fukuoka Prefectural GovernmentInventors: Taro Kimura, Masami Mizu, Kazuo Sakurai, Seiji Shinkai, Kazuya Koumoto
