Publication number: 20120077223Abstract: Optimized enzymatic conditions incorporate a single oxygen atom into digested peptides using a peptidase. The incorporation of a single oxygen atom is especially useful for proteolytic 18O labeling in comparative proteomics. The optimized proteolytic 18O labeling minimizes the generation of a mixture of isotopic isoforms of the peptides resulting from incorporation of either one or two 18O atoms. The outcome is accurate quantification of isotopically labeled peptides.Type: ApplicationFiled: December 5, 2011Publication date: March 29, 2012Applicant: University of North DakotaInventors: Masaru Miyagi, K.

Patent number: 7629179Abstract: Surfaces coated with a target-induced fluorescent compound are used to detect target elements, especially trace elements. The target-induced fluorescent compound does not fluoresce when excited at a specific wavelength until it has bound a target element. The use of these coated surfaces provides several benefits including reduced background for greater sensitivity and eliminating the need to separate target-induced fluorescent compound that has not bound target element from target-induced fluorescent compound that has bound target element. Coated nanoparticles are especially useful for detection of target elements.Type: GrantFiled: March 3, 2006Date of Patent: December 8, 2009Assignee: University of North DakotaInventors: Xiaojun Julia Zhao, David T.
