This will inhibit cell precipitation and allow for informative monitoring as signal substrate is added.Type: GrantFiled: November 2, 2007Date of Patent: January 1, 2013Assignee: Thrombinoscope B.V.Inventors: Peter L. A. Giesen, Kerry Tappenden, Wynne Jones

Patent number: 8334108Abstract: The invention relates generally to a new functional protein S assay and kit that is based on the ability of endogenous protein S to prolong clotting time. In the assay procedure, a test plasma sample is diluted with protein S deficient plasma, followed by the addition of purified or recombinant tissue factor (pTF or rTF), purified natural or synthetic phospholipid (pPL or sPL) and activated protein C (APC) or protein C activator (PCA). The clotting time is then measured and compared to a standard curve or a normal control.Type: GrantFiled: November 19, 2008Date of Patent: December 18, 2012Assignee: Instrumentation Laboratory CompanyInventors: Yong Dai, Biqing Ye, Kui Chen, Pau Bruguera, Daniel Lawson, Shamay Tang

Publication number: 20120295291Abstract: The present invention relates to a method for identifying patients for whom there is a high probability of their not benefiting from therapy with clopidogrel. It was found that the thrombocyte activity of a patient makes it possible to establish, even before the intake of clopidogrel, whether the patient has an increased risk of clopidogrel resistance (high on-treatment platelet reactivity).Type: ApplicationFiled: May 18, 2012Publication date: November 22, 2012Applicant: SIEMENS HEALTHCARE DIAGNOSTICS PRODUCTS GMBHInventor: Andreas Rechner

Patent number: 8313710Abstract: A multilayered optical sensing patch, for the measurement of conditions, such as pH, oxygen level, etc, within containers, is provided. The multilayered optical sensing patch of the present invention is comprised of a heat sealable polymer substrate layer, and a polymeric sensing membrane later attached thereto. The polymer sensing membrane layer is formed of a porous polymer support membrane, and an optical sensing composition (comprising a reactive indicator) covalently bonded thereto. The heat sealable polymer substrate layer is capable of being securely bonded to the inner layer of bioreactor bags, as well as the porous polymer support substrate layer. Further, the porous polymer support membrane layer provides a firm supporting structure for the polymeric sensing layer, thereby protecting the optical sensing composition disposed therein from degradation/damage.Type: GrantFiled: May 16, 2008Date of Patent: November 20, 2012Assignee: Polestar Technologies, Inc.Inventor: James A Kane
