Abstract: Highly specific and novel methods for analyzing glycans and proteoglycans are provided. The present invention provides glycan-reactive isobaric Aldehyde-Reactive Tags (iARTs) and the quantification of iARTs-labeled glycans by tandem mass spectrometry. The iARTs have an amine as an active group to react with aldehyde at the reducing end of glycans through reductive amination and demonstrated complete labeling. Due to the isobaric nature of the iARTs, differentially labeled glycans do not differ in mass, and quantitative information is provided by the isotope-encoded reporter ions generated from MS/MS or MS3 spectra. Quantitative information is thus derived from signal of the reporter ions on same precursor. Uses of the information generated by the inventive methods for diagnosis and treatment are also disclosed.

Abstract: A virtual data center allocation architecture with bandwidth guarantees that provides for the creation of multiple virtual data centers from a single physical infrastructure. The virtual data center allocation is accomplished in three steps. First, clusters are created from the servers in the physical infrastructure. Second, a bipartite graph is built to map the virtual machines to the servers located in a particular cluster and finally a path is calculated between two virtual machines. The virtual data centers may be dynamically expanded or contracted based on changing bandwidth guarantees.
