Patent number: 8008026Abstract: The present invention relates to a method for differentially detecting a multimeric form from a monomeric form of a multimer-forming polypeptide in a biosample, which comprises the steps of: (a) preparing a carrier-capturing antibody conjugate by binding a capturing antibody to the surface of a solid phase carrier in a three dimensional manner, wherein the capturing antibody is capable of recognizing an epitope on the multimer-forming polypeptide; (b) preparing a detection antibody, wherein an epitope recognized by the detection antibody is present at a position in the multimer-forming polypeptide to cause a steric hindrance by the capturing antibody bound to its epitope to prevent the binding of the detection antibody to the multimer-forming polypeptide; (c) contacting simultaneously the carrier-capturing antibody conjugate and the detection antibody to the biosample; and (d) detecting the formation of a carrier-capturing antibody-multimeric form-detection antibody complex.Type: GrantFiled: April 20, 2007Date of Patent: August 30, 2011Assignee: Peoplebio, Inc.Inventors: Seong Soo Alexander An, Kun Taek Lim, Hyun Jung Oh

Patent number: 8003341Abstract: The ATP amplification method is a method for amplifying and detecting a very trace amount of exogenous ATP by allowing a fusion protein (PPK-ADK) of a polyphosphate kinase and an adenylate kinase, the fusion protein not containing ADP, to act on a mixture of ATP, AMP, and a polyphosphate compound. Also provided is an ultrasensitive ATP amplification method by which ATP at a single cell level can be amplified and detected, and an ultrasensitive microbial assay based on this ATP amplification method.Type: GrantFiled: April 28, 2010Date of Patent: August 23, 2011Assignee: Japan Science and Technology AgencyInventor: Akio Kuroda

Patent number: 7998697Abstract: The present invention relates to a method for detecting the presence or non-presence of an endotoxin, characterized in that an OmpT protein is brought into contact with a sample suspected of containing an endotoxin and the protease activity of the OmpT protein is assayed. It also relates to a method for detecting early onset of septicaemia using the inventive method and a kit for performing the method.Type: GrantFiled: November 2, 2006Date of Patent: August 16, 2011Assignee: Bioproduce Sthlm ABInventors: Gen Larsson, Per-Åke Nygren
