Patent number: 8592642Abstract: Disclosed is an evaluation method which can rapidly discriminate a Dao?/? homozygote from a large number of animals produced in a mating experiment between a DAO enzyme deficient mouse and other disease model mice, to rapidly perform a quantitative measurement of the D-amino acids contained in a large number of samples. The invention provides a method for evaluating the effect of a test condition on a mouse tissue, or cultured tissue cells derived from the tissue. The method comprises the steps of: providing a Dao1?/? mouse or the like; exposing the tissue from the Dao1?/? mouse or the like, to the test condition; and analyzing the effect of exposing the tissue from the Dao1?/? mouse or the like, to the test condition.Type: GrantFiled: July 31, 2009Date of Patent: November 26, 2013Assignees: Kyushu University, National University Corporation, Shiseido Company, Ltd.Inventors: Kenji Hamase, Kiyoshi Zaitsu, Masashi Mita, Yutaka Ashida, Yousuke Toujo
