A high analytical sensitivity in ultraviolet matrix-assisted laser desorption ionization mass spectrometry (MALDI-MS) is only achieved if the laser wavelength corresponds to a high optical absorption of the matrix. Laser fluence and the physicochemical properties of the compounds, e.g., the

Phosphatidylethanolamines (PEs) are abundant lipid constituents of the cellular membrane. The amino group of PEs exhibits high reactivity with hypochlorous acid that is generated under inflammatory conditions in vivo. The analysis of the resulting PE mono- and dichloramines is of

Peptide Mass Fingerprinting (PMF) of tryptically in-gel digested samples is a well-established protein identification technique for MALDI mass spectrometry but an in-depth PMF evaluation for in-gel digestions of less specific enzymes is still missing. This study demonstrates that the MALDI-LTQ-Orbitrap

Matrix-assisted laser desorption ionization (MALDI) has become an enabling technology for the fields of protein mass spectrometry (MS) and proteomics. Despite its widespread use, for example, in protein identification via peptide mass fingerprinting, a comprehensive model for the generation of

Due to its sensitivity, the tolerance of impurities and the simplicity of performance, matrix-assisted laser desorption and ionization time-of-flight (MALDI-TOF) mass spectrometry (MS) is increasingly used to analyze lipids from biological sources. Although its detailed role is not understood so
