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

Patent number: 7364911Abstract: The invention provides methods for labeling a molecule by contacting a sample molecule with a solid support coupled to a chemical group comprising a cleavable functional group, one or more functional groups, and a reactive group for the sample molecule, under conditions allowing the sample molecule to covalently bind to the reactive group; and cleaving the cleavable functional group, thereby releasing the sample molecule comprising the one or more functional groups, which can be a tag. The invention also provides a solid support covalently coupled to a chemical group comprising a cleavable functional group, a mass spectrometry tag and a reactive group for covalently attaching a sample molecule, wherein the cleavable functional group, the tag and the reactive group are positioned relative to each other to allow transfer of the tag to the sample molecule upon cleavage of the cleavable functional group.Type: GrantFiled: May 14, 2002Date of Patent: April 29, 2008Inventors: Rudolf H. Aebersold, Huilin Zhou, Beate Rist, George J. Vella, Subhasish Purkayastha, Sasi Pillai

Patent number: 6629040Abstract: The present invention provides methods and reagents for identifying specific masses of compounds in a complex mixture. In particular, the present invention describes an isotope distribution encoded tag (IDEnT) concept wherein the ability to distinguish an analyte encoded with a non-native isotope from those not encoded with the isotope or from those encoded with a different isotope is used for protein identification, enzyme active site identification, peptide sequencing, and the like. Reagents used in the IDEnT strategy consist of a chemical element with a unique isotope distribution not normally found in the analyte class being studied, chemically bonded to, or an integral part of a chemical reagent with a high selectivity of affinity for specific functional group in the analyte.Type: GrantFiled: March 20, 2000Date of Patent: September 30, 2003Assignees: University of Washington, Battelle Memorial InstituteInventors: David R.
