Patent number: 8609423Abstract: The present invention provides methods and compositions for labeling, separating and analyzing proteins, particularly a specific protein of interest within a cell lysate or in a mixture of proteins. The proteins are labeled with an amine reactive or thiol reactive fluorescent dye, or an amine reactive fluorogenic reagent that becomes fluorescent upon reacting to amine groups located on the protein. Following the labeling step, the proteins within the mixture can be separated and analyzed. In a further embodiment, a tag binding fluorogenic reagent that can bind to a tag on a tagged protein is added to specifically label the protein of interest.Type: GrantFiled: May 16, 2008Date of Patent: December 17, 2013Assignee: Life Technologies CorporationInventors: Thomas Diller, George Hanson, Bethany Sutton, Timothy Updyke

Publication number: 20130330754Abstract: The present application is directed to a novel approach for rapid, selective and sensitive detection of heavy metals using a solid-phase bioactive lab-on-paper sensor that is ink-jet printed with sol-gel entrapped reagents to allow colorimetric visualization of the enzymatic activity. The bioactive paper assay is able to detect a range of heavy metals, either alone or as mixtures, in as little as 10 min. The paper-based assay was immune to interferences from non-toxic metal ions such as Na+ or K+, could be used to detect heavy metals that were spiked into tap water or lake water, and provided quantitative data that was in agreement with values obtained by atomic absorption. The paper-based sensor is of value for rapid, on-site screening of trace levels of heavy metals in resource limited areas and developing countries.Type: ApplicationFiled: June 7, 2013Publication date: December 12, 2013Applicant: MCMASTER UNIVERSITYInventors: John Brennan, Zakir Hossain
