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

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

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

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

The performance of the recently developed 4-chloro-alpha-cyanocinnamic acid (Cl-CCA) matrix-assisted laser desorption ionization mass spectrometry (MALDI MS) matrix was investigated in comparison to the most widely used matrix alpha-cyano-4-hydroxycinnamic acid (CHCA). For this purpose, in-solution digestions of standard proteins in
