Recent Patents of Interest in Proteomics

US Patent No. 8,401,800. Molecular flux rates through critical pathways measured by stable isotope labeling in vivo, as biomarkers of drug action and disease activity. Inventor: Marc Hellerstein. Assignee: University of California

Covers a method of measuring molecular flux rates within biomolecular processes involved in disease pathogenesis and comparing them between subjects and controls to obtain information on drug efficacy or toxicity.

US Patent No. 8,399,830. Means and method for field asymmetric ion mobility spectrometry combined with mass spectrometry. Inventors: Andrew Park; Andrew Kaplan; Mark Ridgeway; Gary Glish. Assignee: Bruker Daltonics; University of North Carolina at Chapel Hill

Covers a method for combining field asymmetric ion mobility spectrometry (FAIMS) with mass spectrometry by creating smooth geometric transitions between the channel in the FAIMS analyzer and the channel in the capillary leading to the mass analyzer.

US Patent No. 8,399,827. Mass spectrometry systems. Inventor: Robert Grothe. Assignee: Cedars-Sinai Medical Center

Covers methods related to mass spectrometry systems such as calibration methods and methods for identification of peptides and proteins including a phase-modeling analysis technique.

US Patent No. 8,399,402. Polypeptide as standard for proteome analysis. Inventors: Robert Beynon; Simon Gaskell; Julie Pratt; Claire Eyers. Assignee: Polyquant

Covers a polypeptide for use as a standard in mass spec-based peptide analysis where the analysis consists of at least 16 peptides selected from an established group of peptides along with an artificial protein comprising the polypeptide.

US Patent No. 8,399,383. Protein chips for high throughput screening of protein activity. Inventors: Michael Snyder; Mark Reed; Heng Zhu; James Klemic. Assignee: Yale University.

Covers the creation of protein chips containing densely packed reaction wells for large-scale studies of protein function as well as methods of the using the chips to assay the presence, amount, or function of proteins present in a sample.

US Patent No. 8,399,260. Method for concentration of low-molecular-weight proteins and peptides in body fluid sample. Inventors: Yoshio Kodera; Tadakazu Maeda; Yusuke Kawashima. Assignee: School Juridical Person Kitasato Institute
