Time of flight secondary ion mass spectrometry has been used to better understand the influence of molecular environment on the relative ion yields of membrane lipid molecules found in high abundance in a model mammalian cell line, RAW264.7. Control lipid mixtures were prepared to simulate lipid-lipid interactions in the inner and outer leaflet of cell membranes. Compared with its pure film, the molecular ion yields of 1,2-dioleoyl-sn-glycero-3-phosphocholine and 1-palmitoyl-2-oleoyl-sn-glycero… Expand

ToF-SIMS as a tool for profiling lipids in cancer and other diseases
Abstract Time of flight-secondary ion mass spectrometry (ToF-SIMS) is an ideal technique for probing lipids in situ in cells and other biological material. Sophisticated advances in instrumentationExpand
Matrix effects in biological SIMS using cluster ion beams of different chemical composition.
The presence of water in the cluster beam is associated with a reduction in the observed matrix effects, suggesting that chemically reactive ion beams may provide a route to more quantitative SIMS analysis of complex biological systems. Expand
Reduce the matrix effect in biological tissue imaging using dynamic reactive ionization and gas cluster ion beams.
The results show that the protonated lipid species are increased by ∼10-fold, but that the normally prevalent salt adducts are virtually unaffected, which is discussed as a novel approach to minimizing SIMS matrix effects in complex materials. Expand
ToF-SIMS of tissues: "lessons learned" from mice and women.
Results show that the FFPE can potentially be used as a tissue sample preparation protocol for ToF-SIMS analysis if a cluster ion pre-sputter is used prior to analysis and if nonlipid related tissue features are the features of interest. Expand
Dye-Enhanced imaging of mammalian cells with SIMS.
The ability to chemically map a larger variety of organelles and cellular components will allow for further possible study of a greater number of biological pathways and processes, as well as make cell-drug studies more feasible using SIMS. Expand


Influence of molecular environment on the analysis of phospholipids by time-of-flight secondary ion mass spectrometry.
ToF-SIMS studies of simplistic phospholipid LB model membrane systems demonstrate the potential use of these systems in time-of-flight secondary ion mass spectrometry (TOF- SIMS) analysis of cells. Expand
Molecular organization of cholesterol in unsaturated phosphatidylethanolamines: X-ray diffraction and solid state 2H NMR reveal differences with phosphatidylcholines.
The finding that solubility of cholesterol in sn-1 saturated PEs depends on the amount of polyunsaturation in the sn-2 chain of PE differs from the equivalent PCs that universally incorporate approximately 50 mol % sterol. Expand

We discuss the potential of cluster ion beams for overcoming difficulties experienced within molecular analysis in conventional static secondary ion mass spectrometry (SIMS). Consideration ofExpand
Suppression and enhancement of non-native molecules within biological systems
Abstract With the aim of evaluating the potential of SIMS to provide molecular information from small molecules within biological systems, here we investigate the effect of different biologicalExpand
Dimyristoylphosphatidylcholine/C16:0-ceramide binary liposomes studied by differential scanning calorimetry and wide- and small-angle x-ray scattering.
The thermal phase behavior and structure of fully hydrated binary membranes composed of dimyristoylphosphatidylcholine and N-palmitoyl-ceramide were resolved in further detail by high-sensitivity differential scanning calorimetry (DSC) and x-ray diffraction and a partial phase diagram was constructed.

Liquid domains in vesicles investigated by NMR and fluorescence microscopy.
The results reemphasize the complex phase behavior of cholesterol-containing membranes and provide a framework for interpreting (2)H-NMR experiments in similar membranes. Expand
Influence of Cholesterol on the Biophysical Properties of the Sphingomyelin/DOPC Binary System
This work provides an artificial model for the study of rafts and caveolae on biological membranes and indicates that cholesterol slightly increases the motion of phosphate groups of the lipids in the presence of cholesterol. Expand
Kdo2-Lipid A, a TLR4-specific Agonist, Induces de Novo Sphingolipid Biosynthesis in RAW264.7 Macrophages, Which Is Essential for Induction of Autophagy*
It is established that KLA induces profound changes in sphingolipid metabolism and content in this macrophage-like cell line, apparently to produce sphingoipids that are necessary for formation of autophagosomes, which are thought to play important roles in the mechanisms of innate immunity. Expand
Salt effects on ion formation in desorption mass spectrometry: an investigation into the role of alkali chlorides on peak suppression in time-of-flight-secondary ion mass spectrometry.
Data from the analysis of the frozen-hydrated samples is presented that shows both an ion yield enhancement and a significant amelioration of the salt suppression effects when compared to the samples run under standard conditions, demonstrating that it is a helpful approach to dealing with salt suppression.

Sphingomyelin is much more effective than saturated phosphatidylcholine in excluding unsaturated phosphatidylcholine from domains formed with cholesterol
It is found that acyl chain 2H‐labeled DOPC is much less ordered in SM‐containing mixtures than in those containing DPPC, suggesting that DOPP in the SM‐ containing mixture senses a lower concentration of cholesterol in its direct environment. Expand
