Patent number: 10788499Abstract: The present disclosure provides assays for lysosomal enzymes, specifically palmitoyl protein thioesterase 1 (PPT1) and tripeptidyl peptidase 1 (TPP1), using, for example, tandem mass spectrometry. The assays involve the detection of enzymatic products obtained through the action of the lysosomal enzymes on new enzyme substrates, and can be used for quantitative enzyme activity measurements. The assays for the enzymes utilize a minimum steps for sample work up and can be run in a simplex format or in a duplex format for the detection of neuronal ceroid lipofuscinoses, or in a multiplex format with other mass spectrometry-based assays for screening of neuronal ceroid lipofuscinoses and other lysosomal storage disorders.Type: GrantFiled: July 13, 2016Date of Patent: September 29, 2020Assignee: University of WashingtonInventors: Michael H.

Patent number: 7544518Abstract: Analytical reagents and mass spectrometry-based methods using these reagents for the rapid, and quantitative analysis of proteins or protein function in mixtures of proteins. The methods employ affinity labeled protein reactive reagents having three portions: an affinity label (A) covalently linked to a protein reactive group (PRG) through a linker group (L). The linker may be differentially isotopically labeled, e.g., by substitution of one or more atoms in the linker with a stable isotope thereof. These reagents allow for the selective isolation of peptide fragments or the products of reaction with a given protein (e.g., products of enzymatic reaction) from complex mixtures. The isolated peptide fragments or reaction products are characteristic of the presence of a protein or the presence of a protein function in those mixtures. Isolated peptides or reaction products are characterized by mass spectrometric (MS) techniques.Type: GrantFiled: November 23, 2004Date of Patent: June 9, 2009Assignee: University of WashingtonInventors: Rudolf Hans Aebersold, Michael H.

Patent number: 6750448Abstract: The present invention provides an instrument and methods for the preparative separation of components of mixtures using mass spectrometric methods. Nondestructive ionization methods are employed to generate ionized components of a mixture, the ionized components are spatially separated by mass and the mass-separated ion components are trapped. The ion source and mass spectrometric techniques employed allow the generation of large ion currents of ion components, on the order of nanoamps, which facilitate rapid accumulation of nanomole quantities of mass-separated components in relatively short times (minutes to hours).Type: GrantFiled: March 10, 2003Date of Patent: June 15, 2004Assignees: University of Washington, Aventis Pharmaceuticals, Inc.Inventors: Frantisek Turecek, Adi Scheidemann, Terry Olney, Frank J.
