Publication number: 20110171736Abstract: The present invention provides novel reactive fluorescent compounds that incorporate stable isotopic (deuterium, 13-carbon, 15-nitrogen, 18-oxygen) substitutions. The invention includes the use of these compounds, in combination with non-isotopically substituted analogs, for the purification, identification and relative quantification of proteins, peptides, saccharides, metabolites, and other biologically important compounds by combining liquid chromatography (LC) and mass spectrometry (MS). Fluorescent labeling of target compounds in this manner provides orders-of-magnitude sensitivity enhancement over traditional stable isotope labels, and also affords the possibility of simultaneous multiplexed analysis due to the multiwavelength nature of different fluorophores.Type: ApplicationFiled: November 11, 2010Publication date: July 14, 2011Applicant: LIFE TECHNOLOGIES CORPORATIONInventors: Brian AGNEW, Kyle Richard Gee

Publication number: 20110118136Abstract: Capture compounds and collections thereof and methods using the compounds for the analysis of biomolecules are provided. In particular, collections, compounds and methods are provided for analyzing complex protein mixtures, such as the proteome. The compounds are multifunctional reagents that provide for the separation and isolation of complex protein mixtures. Each compound has the formula: wherein: Z is a trityl derivative; X, the reactivity function, covalently binds to amino acid side chains of proteins; Y, the selectivity function, modulates binding of X to the amino acid side chains in proteins such that X binds to fewer proteins when Y is present than in its absence; and Q permits separation or immobilization of the capture compound. Automated systems for performing the methods also are provided.Type: ApplicationFiled: November 2, 2010Publication date: May 19, 2011Inventors: Hubert Köster, Suhaib Siddigi, Daniel P. Little
