Desorption Electrospray Ionization-Mass Spectrometry of Proteins [PDF]
Analytical Chemistry, 2007 Desorption electrospray ionization-mass spectrometry (DESI-MS) was evaluated for the detection of proteins ranging in molecular mass from 12 to 66 kDa. Proteins were uniformly deposited on a solid surface without pretreatment and analyzed with a DESI source coupled to a quadrupole ion trap mass spectrometer.

Further characterization of glycine-containing microcystins from the McMurdo Dry Valleys of Antarctica [PDF]
, 2015 Microcystins are hepatotoxic cyclic peptides produced by several cyanobacterial genera worldwide. In 2008, our research group identified eight new glycine-containing microcystin congeners in two hydro-terrestrial mat samples from the McMurdo Dry Valleys ...

Shotgun lipidomics of cardiolipin molecular species in lipid extracts of biological samples
Journal of Lipid Research, 2006 Cardiolipin is a prominent component of the mitochondrial inner membranes contributing to the regulation of multiple discrete mitochondrial functions. Here, we extend shotgun lipidomics to identify and quantitate cardiolipin molecular species directly ...

Recent advances in experimental techniques to probe fast excited-state dynamics in biological molecules in the gas phase : dynamics in nucleotides, amino acids and beyond [PDF]
, 2013 In many chemical reactions, an activation barrier must be overcome before a chemical transformation can occur. As such, understanding the behaviour of molecules in energetically excited states is critical to understanding the chemical changes that these ...

Neutral particle Mass Spectrometry with Nanomechanical Systems [PDF]
, 2015 Current approaches to Mass Spectrometry (MS) require ionization of the analytes of interest. For high-mass species, the resulting charge state distribution can be complex and difficult to interpret correctly.

Ionization and transmission efficiency in an electrospray ionization—mass spectrometry interface [PDF]
Journal of the American Society for Mass Spectrometry, 2007 The ionization and transmission efficiencies of an electrospray ionization (ESI) interface were investigated to advance the understanding of how these factors affect mass spectrometry (MS) sensitivity. In addition, the effects of the ES emitter distance to the inlet, solution flow rate, and inlet temperature were characterized.
