Patent number: 7575884Abstract: The present invention relates to a test piece having a simple structure, by which HDL cholesterol can be measured easily using a small amount of specimen. A reagent layer (2) is formed on a support (1), and an enzyme reagent for measuring cholesterol, a first surfactant that makes a solubility of a high-density lipoprotein (HDL) higher than that of a lipoprotein other than the HDL, and a second surfactant that inhibits the lipoprotein other than the HDL from dissolving are contained in the reagent layer (2).Type: GrantFiled: July 19, 2005Date of Patent: August 18, 2009Assignees: ARKRAY, Inc., Daiichi Pure Chemicals Co., Ltd.Inventors: Hiroshi Tamura, Susumu Nishino, Takehiro Yamaguchi, Koichi Hino

Publication number: 20090197288Abstract: The present invention is intended to provide a method for simultaneously measuring cholesterol in low density lipoprotein and total cholesterol as test components in blood. Specifically, a method is used for simultaneously measuring cholesterol in low density lipoprotein and total cholesterol in a biological sample, whereby cholesterol in low density lipoprotein and total cholesterol in a biological sample are quantified with a single measurement.Type: ApplicationFiled: February 9, 2009Publication date: August 6, 2009Inventor: Hiroshi MATSUI

Publication number: 20090192135Abstract: The present invention relates to the identification and use of single nucleotide polymorphisms and haplotypes in the Niemann Pick C1-Like 1 (NPC1L1) gene. In particular, methods are provided for correlating NPC1L1 polymorphisms and haplo-types with the responsiveness of a pharmaceutically active compound administered to a human subject. The invention further relates to a method for estimating the responsiveness of a pharmaceutically active compound administered to a human subject which method comprises determining at least one polymorphism in the NPC1L1 gene. The methods are based on determining polymorphisms in the NPC1L1 gene and correlating the responsiveness of a pharmaceutically active compound in the human by reference to one or more polymorphism in NPC1L1.Type: ApplicationFiled: March 28, 2006Publication date: July 30, 2009Applicants: SCHERING CORPORATION, MERCK & CO., INC., ROSETTA INPHARMATICS LLCInventors: Jason Samuel Simon, Maha Chabhar Karnoub, Michael E.
