20090233373 | MULTISITE PHOSPHORYLATED PEPTIDE (PROTEIN) RECOGNIZING COMPOUND AND DETECTION METHOD, IMAGING METHOD, ALZHEIMER'S DISEASE DIAGNOSING METHOD AND REAGENT KIT USING THE SAME - There are provided a novel compound which captures a multisite phosphorylated peptide or protein specifically to a phosphorylation site and a method for detecting a multisite phosphorylated peptide or protein using the same. In particular, there are provided a compound which specifically detects an excessively phosphorylated tau protein observed in the brain affected by Alzheimer's disease and a method for diagnosing Alzheimer's disease in vitro or in vivo using the compound. By bringing a metal complex compound having two dipicolylamine (Dpa) moieties and a spacer including a chromogenic or luminescent functional group or atom group into contact with a multisite phosphorylated peptide or protein, the compound recognizes the distance between phosphate groups and specifically binds to the peptide or the protein, and a multisite phosphorylated peptide or protein or a kinase activity is optically detected by measuring the change, or a multisite phosphorylated peptide or protein or kinase activity is imaged by an optical imaging method applying the change in the luminescence. | 09-17-2009 |
20100225314 | NUCLEAR MAGNETIC RESONANCE MEASURING METHOD - The present invention provides a method for measuring nuclear magnetic resonance that employs a compound in which a plurality of nuclei is labeled with isotopes as a probe agent, highly selectively and highly sensitively obtains a nuclear magnetic resonance signal of the above described probe agent, and can attach a spatial positional information to the above described nuclear magnetic resonance signal, and an apparatus therefore. | 09-09-2010 |
20100247444 | COMPOUND, DIAGNOSTIC AGENT, NUCLEAR MAGNETIC RESONANCE ANALYSIS METHOD, NUCLEAR MAGNETIC RESONANCE IMAGING METHOD, MASS SPECTROMETRY METHOD AND MASS SPECTROMETRY IMAGING METHOD - To produce a labeled compound for a selected biological substance not using a radioisotope atom which has a risk of exposure to radioactivity and limitation on handling time but using a stable isotope atom; and that the labeled compound can be measured with good sensitivity separably from naturally occurring compounds of the selected biological substance which are substituted with the stable isotope atom. Choline as a biological substance is labeled by substituting the nitrogen atom of the quaternary ammonium group and all the carbon atoms of the methyl group attached to the nitrogen atom with respective isotopes | 09-30-2010 |
20100248279 | SUBSTRATE PROBE, ENZYME-ACTIVITY DETECTION METHOD BY A MULTI-DIMENSIONAL NUCLEAR MAGNETIC RESONANCE METHOD AND ENZYME-ACTIVITY IMAGING METHOD - Substrate probe capable of detecting enzyme activity with high accuracy and a method for detecting the enzyme activity by a multi nuclear magnetic resonance method using the substrate probe. Multi-dimensional nuclear magnetic resonance is performed by using a substrate probe, which is used for measuring enzyme activity by a multi-dimensional nuclear magnetic resonance method and characterized by containing a enzyme recognition site that is selectively recognized by an active-state enzyme, as at least one constitutional unit, and a group to which at least three nuclear magnetic resonance active nuclei each having a nuclear spin and a different resonance frequency are connected, being present specifically to the enzyme recognition, thereby detecting presence of the substrate probe and the enzyme activity. Alternatively, imaging of the enzyme activity is performed by a multi-dimensional nuclear resonance imaging method. | 09-30-2010 |
