MALDI-TOF continues to be an important tool for many proteomic studies. Recently, a new rationally designed matrix 4-chloro-alpha-cyanocinnamic acid was introduced, which is reported to have superior performance as compared with the "gold standard" alpha-cyano-4-hydroxycinnamic acid (CHCA). In this study

Multiphosphorylated peptides endogenously present in milk exert anticariogenic activity due to their calcium binding capacity. This study performed comprehensive analysis of multiphosphorylated peptides in raw milk using matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Since phosphopeptides are often negatively

Analysis of low molecular weight compounds (LMWC) in complex matrices by vacuum matrix-assisted laser desorption/ionization (MALDI) often suffers from matrix interferences, which can severely degrade limits of quantitation. It is, therefore, useful to have available a range of suitable matrices

This work experimentally verifies and proves the two long since postulated matrix-assisted laser desorption/ionization (MALDI) analyte protonation pathways known as the Lucky Survivor and the gas phase protonation model. Experimental differentiation between the predicted mechanisms becomes possible by the use

The binding of the heme enzyme myeloperoxidase to phosphatidylserine epitopes on the surface of non-vital polymorphonuclear leukocytes and other cells at inflammatory sites favours modifications of this phospholipid by myeloperoxidase products.
