Patent number: 10513676Abstract: Provided is a measurement method whereby the amount of unbound bilirubin (UB) can be exactly reflected whether a specimen contains a large amount of conjugated bilirubin or not. The measurement method for UB according to the present invention comprises decomposition step (i), decomposition stopping step (ii), contact step (iii) and detection step (iv). In decomposition step (i), a blood sample containing unconjugated bilirubin (iD-Bil) and conjugated bilirubin (D-Bil) is subjected to an oxidative decomposition reaction of UB in iD-Bil and D-Bil. In decomposition stopping step (ii), the oxidative decomposition reaction is stopped to give a decomposition product of the sample. In contact step (iii), the decomposition product of the sample is contacted with UnaG that is capable of specifically binding to iD-Bil. Separately, an unreacted sample, which is the blood sample not subjected to decomposition step (i), is contacted with UnaG too.Type: GrantFiled: March 30, 2016Date of Patent: December 24, 2019Assignee: National University Corporation Kobe UniversityInventors: Sota Iwatani, Ichiro Morioka, Hajime Nakamura, Atsushi Miyawaki, Akiko Kumagai

Patent number: 8080531Abstract: ATR kinase is a key regulator of checkpoint responses to incompletely replicated and damaged DNA. Without this checkpoint, cells will enter mitosis prematurely, likely resulting in cell death. The invention provides methods and reagents to either block or activate the activation of the ATR kinase checkpoint, through, for example, either blocking or activating the expression of an ATR activator TopBP1. The invention also provides screening methods to identify additional ToBP1 inhibitors or activators that may be used to modulate the activity of the ATR checkpoint.Type: GrantFiled: July 30, 2008Date of Patent: December 20, 2011Assignee: California Institute of TechnologyInventors: Akiko Kumagai, William Dunphy

Patent number: 7807489Abstract: A light-emitting device with a protection layer for Zn inter-diffusion and a process to form the device are described. The device of the invention provides an active layer containing aluminum (Al) as a group III element, typically AlGaInAs, and protection layers containing silicon (Si) to prevent the inter-diffusion of zing (Zn) atoms contained in p-type layers surrounding the active layer. One of protection layers is put between the active layer and the p-type cladding layer, while, the other of protection layers is disposed between the active layer and the p-type burying layer.Type: GrantFiled: June 18, 2008Date of Patent: October 5, 2010Assignee: Sumitomo Electric Industries, Ltd.Inventors: Mitsuo Takahashi, Kenji Hiratsuka, Akiko Kumagai
