Patent number: 8759007Abstract: The present invention provides a method for detecting modified LDL, abnormal cells or bacteria using an intermolecular interaction analysis method, in which a region involved in ligand recognition by a receptor is expressed, without modification or as a biotinylated protein, in cells or in a test tube, and thereafter, the expressed region or the expressed biotinylated protein is immobilized via avidin or streptavidin to a solid phase while the orientation thereof is maintained, and the immobilized protein is utilized; and a kit for detecting the modified LDL or the like.Type: GrantFiled: December 11, 2009Date of Patent: June 24, 2014Assignee: National Food Research InstituteInventors: Sachiko Machida, Kiyoshi Hayashi, Ken Tokuyasu, Yoshikiyo Sakakibara, Shigeru Matsunaga

Patent number: 8754012Abstract: The present invention relates to methods of screening for expression of a soluble candidate protein within an expression library of candidate proteins. The method involves fusing each candidate protein in the library to a peptide substrate and identifying cells that express soluble candidate protein by detecting enzymatic modification of the peptide substrate.Type: GrantFiled: September 5, 2005Date of Patent: June 17, 2014Assignee: European Molecular Biology LaboratoryInventor: Darren James Hart
