They say it takes several years for an awards program to really get off the ground and start amassing a history, establishing a place for itself in the industry. If this is true, then I believe we can safely say that this year, the LCGC Pittcon Awards have officially arrived. With past Lifetime Achievement Award winners such as Walt Jennings and Harold McNair, and bright young stars such as Gert Desmet and Kevin Schug claiming Emerging Leader honors over the past couple of years, there is a great deal of suspense building over who will win the 2010 awards, set to be presented at Pittcon 2010 in Orlando, Florida.

Continuing a series on peak tailing in chromatography, John Hinshaw discusses the effects that peak tailing has on quantitative measurement of peak height and area.

A new proteomic profiling method based on material-enhanced laser desorption/ionization (MELDI) has been developed to identify candidate biomarkers that are selected in MELDI mass profiles. The basic principle of applying MELDI is to trace out the low-concentration species generated as a result of disease, which can then be used as diagnostic markers after their authentic validation. The first step of the MELDI approach is applied to reduce the complexity of proteomic samples by specific binding of serum proteins onto chemically modified MELDI beads, which are then directly analysed by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry (MS). The resulting mass profiles provide the basis for differentiating diseased samples from control samples. The use of liquid handling robots for sample preparation for high-throughput applications leads to higher reproducibility, which is crucial to succesfully identify disease markers. The ongoing development of MELDI for the..
