This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Glycosaminoglycans (GAGs) are linear sulfated oligosaccharides found attached to core proteins on cell surfaces, in basement membranes and extracellular matrices. These molecules are central to patterning events during animal development and function to bind many families of growth factors and growth factor receptors. Because they are sulfated, glycosaminoglycans pose unique analytical challenges. Tandem mass spectrometry of chondroitin sulfate and heparan sulfate oligosaccharides was pioneered at the BUSM Mass Spectrometry Resource, and staff act to disseminate knowledge to the scientific community. Communication through scientific talks and laboratory demonstrations are forms of dissemination and training whereby transfer of information on GAG MS takes place. The following summarize dissemination and training during 2010-11: Review articles: Zaia, J. """"""""Mass spectrometry and glycomics"""""""" OMICS 2010, 14, 401-18. Zaia, J.
