Publication number: 20030003601Abstract: A biochemical analysis unit is obtained, which comprises a base plate having spot-shaped regions and has identification information, specific binding substances having been fixed respectively to the spot-shaped regions. A labeled organism-originating substance having identification information is subjected to specific binding to the specific binding substances. A label signal corresponding to a position of the spot-shaped region having thus been labeled selectively is read out to form data for a biochemical analysis. The identification information of the biochemical analysis unit and the identification information of the organism-originating substance are acquired and fed into an analysis apparatus, such that the correspondence relationship between the two pieces of the identification information is clear.Type: ApplicationFiled: July 1, 2002Publication date: January 2, 2003Applicant: FUJI PHOTO FILM CO., LTD.Inventors: Masato Some, Katsuaki Muraishi, Hitoshi Shimizu, Nobuhiko Ogura, Tohru Tsuchiya, Hirohiko Tsuzuki
