There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

"Membrane-targeted Probes for Localized Superoxide Detection during Cell"
Reactive oxygen species (ROS) are produced in a number of cell signaling pathways. Characterization of local ROS is essential in elucidating the role of ROS in signaling due to the short half-lives and low concentrations of ROS. Current methods do not differentiate ROS production by membrane-bound NADPH oxidases from other sources. In this work, we have developed a method for detecting local superoxide production at the cell membrane.

"Purification of Cardiomyocytes from Differentiating Human Pluripotent Stem Cells using Molecular Beacons Targeting Cardiomyocyte-specific mRNA"
Studies have shown that differentiated cells must be used for regenerative heart therapies. We hypothesized that mRNA targets could be used as novel targets for high throughput FACS separation to isolate high purity cardiomyocytes. We designed molecular beacons targeting cardiac genes and used them to separate cardiomyocytes from a culture of hESCs or hiPSCs. We generated a >98% pure population of cardiomyocytes from a differentiating culture.
