The 1-phenyl-3-methyl-5-pyrazolone (PMP) derivatives of monosaccharides, maltooligosaccharides, and oligosaccharides enzymatically released from asparagine-linked sites in ribonuclease B and fetuin have been investigated using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Use of the matrix 2,6-dihydroxyacetophenone containing diammonium hydrogen citrate (DHAP/DAHC)

Selecting an appropriate matrix solution is one of the most effective means of increasing the ionization efficiency of phosphopeptides in matrix-assisted laser-desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). In this study, we systematically assessed matrix combinations of 2, 6-dihydroxyacetophenone (DHAP) and diammonium

2,5-Dihydroxyacetophenone (DHAP) is presented as a matrix which enables highly sensitive matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometric analysis of peptides, proteins and glycoproteins on AnchorChip targets. Depending on the protein, lower fmol amounts can be detected due to the
