Patent number: 10196668Abstract: Reagents, methods, and kits for assaying enzymes associated with lysosomal storage diseases MPS-I, MPS-II, MPS-IIIA, MPS-IIIB, MPS-IV A, MPS-VI, and MPS VII. In one aspect, the invention provides methods for assaying one or more enzymes associated with a lysosomal storage disease. In a first embodiment, the method includes: (a) contacting a sample with a first solution to provide a solution comprising one or more lysosomal enzymes; (b) contacting the one or more lysosomal enzymes in solution with an enzyme substrate for each lysosomal enzyme to be analyzed and incubating the substrates with the enzymes for a time sufficient to provide a solution comprising an enzyme product for each lysosomal enzyme present in the sample.Type: GrantFiled: September 5, 2014Date of Patent: February 5, 2019Assignee: University of Washington through its Center for CommercializationInventors: Michael H. Gelb, Arun Babu Kumar, Frances Hocutt, Zdenek Spacil, Mariana Natali Barcenas Rodriguez, Frantisek Turecek, C. Ronald Scott

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. Gelb, Steven P. Gygi, C. Ronald Scott, Frantisek Turecek, Scott A. Gerber, Beate Rist
