Epithelial ovarian carcinoma diagnosis by desorption electrospray ionization mass spectrometry imaging

Scientific Reports, 2016
Ovarian cancer is highly prevalent among European women, and is the leading cause of gynaecological cancer death. Current histopathological diagnoses of tumour severity are based on interpretation of, for example, immunohistochemical staining. Desorption

Nanobubbles in Electrospray Ionization Mass Spectrometry

Analytical Chemistry
Nanobubbles (NBs) are very small gas-filled cavities in solvents, and when their sizes reach diameters around 200 nm, they remain in solution for extended periods of time, featuring special chemical and physical properties. Here, we investigate the application of NBs in electrospray ionization.

The path of biomolecular mass spectrometry into open research

Nature Communications, 2019
Originally designed for measuring isotope abundances and elemental masses, mass spectrometry is becoming a mainstay across life sciences. As electrospray ionization of biomolecules turns 30 and the Orbitrap mass analyzer 20, we take this opportunity to ...

Characterization of lead-phytochelatin complexes by nano-electrospray ionization mass spectrometry

Frontiers in Microbiology, 2012
The role of phytochelatins (PCn, metal-binding oligopeptides with the general structure (γGlu - Cys)n - Gly (n = 2- 11)) in metal detoxification is assumed to be based on immobilization of metals, which prevents binding of metals to important ...

Seminolipid and its precursor/degradative product, galactosylalkylacylglycerol, in the testis of saposin A- and prosaposin-deficient mice

Journal of Lipid Research, 2003
Sphingolipid activator proteins (saposins A, B, C, and D) are derived from a common precursor protein (prosaposin) and specifically activate in vivo degradation of glycolipids with short carbohydrate chains.

Comprehensive Molecular Characterization of Atmospheric Brown Carbon by High Resolution Mass Spectrometry with Electrospray and Atmospheric Pressure Photoionization.

Analytical Chemistry, 2018
Light-absorbing components of atmospheric organic aerosols, which are collectively termed "brown carbon" (BrC), are ubiquitous in the atmosphere. They affect absorption of solar radiation by aerosols in the atmosphere and human health as some of them ...

An Organic Chemist’s Guide to Electrospray Mass Spectrometric Structure Elucidation

Molecules, 2019
Tandem mass spectrometry is an important tool for structure elucidation of natural and synthetic organic products. Fragmentation of odd electron ions (OE+) generated by electron ionization (EI) was extensively studied in the last few decades, however ...
