03/13/07 - The LIPID MAPS Consortium is conducting an open Workshop on "Lipidomics" at Experimental Biology 2007 under the auspices of the American Society for Nutrition. A panel of eight experts will discuss methods that have been developed under an NIH (NIGMS) "Glue-grant" for analysis of neutral glycerolipids, phospholipids, eicosanoids, sterols, sphingolipids, prenols and various novel lipids by mass spectrometry as well as related issues such as sample extraction, internal standards, data handling and display, and nomenclature. In addition to reviewing the LIPID MAPS protocols, the panel will invite questions and discussion regarding these issues and the directions of future lipidomics research and developments. The workshop will be held in the Grand Ballroom South of the Renaissance Hotel, 999 Ninth Street NW, Washington, DC, from 8 am to 1 pm on Saturday, April 28, 2007, including an hour for open discussion over snacks. Attendance is free (registration for FASEB Experimental Biology is not required), but persons who are interested in attending are encouraged to contact Al Merrill. "Walk ins" are also welcome. Funding for the workshop has been provided by the LIPID MAPS Glue grant (U54 GM069338), Avanti Polar Lipids and Applied Biosystems.
