Exosomes are small lipid membrane-bound extracellular vesicles, on the order 30 – 150 nm in diameter, which are shed by normal and tumor cells in the body. They are circulating within your body and can be isolated from virtually any biological fluid. Exosomes released from tumor cells have been shown to be enriched in certain proteins. These nanobodies hold significant promise for the discovery of cancer biomarkers, for cancer diagnosis and prognosis, and for biomarker quantitation.

The Wednesday afternoon session “Metabolomics: Untargeted Profiling,” will be held 2:30–4:30 pm in the Murphy Ballroom. The session, chaired by Elizabeth J. Want of Imperial College London, in London, United Kingdom, addresses six developments in this area.

A morning session today on “Environmental: Innovative Approaches and Instrumentation,” will be held 8:30–10:30 am in Room B308–309. The session, chaired by Pierangela Palma of the University of Urbino, in Urbino, Italy, includes talks on a range of mass spectrometry techniques.

“Forensics: Innovations and Applications” will be held this afternoon from 2:30 to 4:30 pm in Room B405-407. The session, chaired by Travis M. Falconer, a chemist with the Forensic Chemistry Center of the US Food & Drug Administration in Cincinnati, Ohio, includes topics on analytes ranging from explosives to larvae.

Modern HPLC method development is dominated by a small number of pH adjusting reagents and buffers that are prevalent even when the method uses UV detection. This is driven primarily by the requirements of mass spectrometry.

The Research Awards will be presented today, at the beginning of the Biemann Medal Lecture session in the Murphy Ballroom, at 4:45 pm.

The Tuesday morning oral sessions on “Environmental: Emerging Contaminants” -in Honor of Ron Hites-will be held 8:30-10:30 am in Room B308–309. The session, chaired by Susana Y. Kimura of the Department of Chemistry at University of Calgary in Calgary, in Alberta, Canada, addresses analytical strategies for a range of environmental contaminants.

The Tuesday afternoon session on “Instrumentation: Innovative Separations Approaches Coupled to MS,” will be held 2:30-4:30 pm in the Auditorium of Building A. The session, chaired by Xing-Fang Li of the Department of Laboratory Medicine and Pathology at the University of Alberta, in Edmonton, Alberta, Canada, addresses analyses related to biology, proteomics, environmental studies, petroleum, and more.

The morning session “Imaging: Instrumentation & Method Development,” will be held from 8:30 to 10:30 am in Room B302–305. The session, chaired by Martina Marchetti-Deschmann of the Faculty of Technical Chemistry at TU Wien in Wein, Austria, includes talks on a variety of aspects of mass spectrometry imaging.
