Patent number: 10544453Abstract: There is provided an apparatus for detecting a nucleic acid amplification product in real time, which is capable of effectively excluding or reducing apparatus error factors without using a second fluorescence signal used for correction. A plurality of wells 7A are given with temperature cycles and fluorescence strength from a nucleic acid amplification product is detected in real time in each well 7A. A fluorescence measurement value [DNA]raw obtained from the well 7A and a fluorescence measurement value [DNA]bg obtained from a connection wall near the well 7A are detected, and the fluorescence measurement value [DNA]bg is subtracted from the fluorescence measurement value [DNA]raw to determine fluorescence strength [DNA]real of the well 7A.Type: GrantFiled: July 23, 2014Date of Patent: January 28, 2020Assignee: PHC HOLDINGS CORPORATIONInventors: Yuichi Tamaoki, Akifumi Iwama, Yasuaki Sonoda
