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

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

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
