Recent Patents of Interest in Proteomics

US Patent No. 7,973,134. Reagents for the detection of protein phosphorylation in anaplastic large cell lymphoma signaling pathways. Inventors: Albrecht Moritz, Kimberly Lee, John Rush, Roberto Polakiewicz. Assignee: Cell Signaling Technology

Discloses 211 novel phosphorylation sites in signal transduction proteins underlying anaplastic large cell lymphoma and provides phosphorylation-site-specific antibodies and heavy-isotope labeled peptides for their detection and quantification.


US Patent No. 7,972,827. Photoswitchable method for the ordered attachment of proteins to surfaces. Inventors: Julio Camarero, James DeYoreo, Youngeun Kwon. Assignee: Lawrence Livermore National Security

Covers a method of attaching proteins to any solid support with control over their orientation of attachment using UV-light activation. Enables the creation of protein arrays using standard photolithographic techniques.


US Patent No. 7,972,802. Lipoprotein-associated markers for cardiovascular disease. Inventors: Jay Heinecke, Tomas Vaisar. Assignee: University of Washington

Covers a method of screening mammalian subjects for one or more lipoprotein-associated biomarkers to determine if the subject is suffering from, or at risk of developing, cardiovascular disease.


US Patent No. 7,972,788. Skin aging marker and technique for use thereof. Inventors: Satoshi Miyata, Kaoru Miyazaki, Chie Yasuda, Akihiro Iwamatsu. Assignees: Fancl, Yokohama City University, Kihara Memorial Yokohama Foundation for the Advancement of Life Sciences, Kirin Holdings
