Patent number: 11649311Abstract: There is provided a method for introducing a temperature-sensitive probe comprising a copolymer, which comprises a thermoresponsive unit and a fluorescent unit, into a cell, and the method using the copolymer further comprising a cationic unit as the temperature-sensitive probe, and the method comprising the step of mixing the copolymer with the cell in a solvent. The copolymer can be preferably used as a fluorescence temperature sensor which measures intracellular temperature since the copolymer has a cationic group and thus enters into a cell without using a special method.Type: GrantFiled: December 13, 2018Date of Patent: May 16, 2023Assignees: KIRIN HOLDINGS KABUSHIKI KAISHA, THE UNIVERSITY OF TOKYOInventors: Toshikazu Tsuji, Kumiko Ikado, Seiichi Uchiyama, Kyoko Kawamoto

Publication number: 20080096266Abstract: The present invention provides a method for stabilizing an antiallergic activity of lactic acid bacteria against a high-temperature treatment and a composition for the stabilization, which can maintain an antiallergic activity of lactic acid bacteria against a high-temperature treatment, and foods and drinks such as drinks having a stabilized antiallergic activity of lactic acid bacteria, and a method for producing the same. The antiallergic activity of lactic acid bacteria can be maintained stably by making the lactic acid bacteria and polyphenols coexist, even when high-temperature treatments are conducted. As polyphenols used in the present invention, polyphenols extracted from a plant such as green tea-derived polyphenols can be used. In the present invention, various lactic acid bacteria having an antiallergic activity can be used, and in particular, lactic acid bacteria having a high antiallergic activity can be advantageously used as such lactic acid bacteria.Type: ApplicationFiled: September 8, 2005Publication date: April 24, 2008Inventors: Toshihiro Komeda, Kumiko Ikado, Koichiro Yamauchi, Akira Saiki, Kiyoko Sadakari
