Publication number: 20130259872Abstract: An antibody binding to IPC was obtained by using an animal cell in which a cell membrane protein associatable with ILT7 was co-expressed as an immunogen. The antibody of the invention has a high specificity which allows immunological distinction between other ILT family molecules and ILT7. The anti-ILT7 antibody of the invention bound to IPC and inhibited the activity thereof. With the anti-ILT7 antibody of the invention, the IPC activity can be inhibited and an interferon-related disease can be treated or prevented. ILT7 expression is maintained even in IPC in the presence of IFN?. Therefore, an inhibitory action of IPC activity by the anti-ILT7 antibody can be expected even in an autoimmune disease patient with an increased production of IFN?.Type: ApplicationFiled: June 7, 2013Publication date: October 3, 2013Inventors: Yumiko Kamogawa, Minkwon Cho, Naoko Arai, Koji Ishida

Patent number: 8529896Abstract: BST2 antibodies were selected by using as an indicator the binding between BST2 antibodies and various splicing variants of human BST2 antigen. As a result, the present inventors successfully obtained BST2 antibodies that specifically recognize BST2D, which has been reported to be expressed at high levels in cancer cells. The antibodies of the present invention specifically bind to cells expressing BST2D. Non-specific antibody binding to non-target tissues, which results in the decrease of antibody concentration in blood, can be prevented by using the antibodies of the present invention therapeutically. Alternatively, the present invention provides diagnostic agents comprising an antibody of the present invention, which specifically detect tissues expressing BST2D.Type: GrantFiled: October 16, 2008Date of Patent: September 10, 2013Assignees: SBI Biotech Co., Ltd., Chugai Seiyaku Kabushiki KaishaInventors: Yumiko Kamogawa, Sahori Namiki, Minkwon Cho, Koji Ishida

Patent number: 8436352Abstract: Whether there is a defect such as chipping of a die or separation of a resin in a wafer level package is electrically detected. A peripheral wiring is disposed along four peripheries of a semiconductor substrate outside a circuit region and pad electrodes P1-P8. The peripheral wiring is formed on the semiconductor substrate and is made of a metal layer that is the same layer as or an upper layer of a metal layer forming the pad electrodes P1-P8, or a polysilicon layer. A power supply electric potential Vcc is applied to a first end of the peripheral wiring, while a ground electric potential Vss is applied to a second end of the peripheral wiring through a resistor R2. A detection circuit is connected to a connecting node N1 between the peripheral wiring and the resistor R2, and is structured to generate an anomaly detection signal ERRFLG based on an electric potential at the connecting node N1.Type: GrantFiled: June 9, 2011Date of Patent: May 7, 2013Assignee: ON Semiconductor Trading, Ltd.Inventors: Yoshinobu Kaneda, Koji Ishida
