Laserspray ionization (LSI) mass spectrometry (MS) allows, for the first time, the analysis of proteins directly from tissue using high performance atmospheric pressure ionization mass spectrometers. Several abundant and numerous lower abundant protein ions with molecular masses up to ∼20,000

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
MALDI mass spectrometry in the solution of some forensic problems.
A new, selective, straightforward and general method for preparation of highly functionalized coronands or spiro derivatives bearing 1,2-dihydroxyacetophenone unit, under conventional conditions and ultrasonic irradiation, is reported. The reaction setup involves only one step, acylation of an α-chloro-3,4-dihydroxyacetophenone with phthaloyl

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
