A variety of gram-positive and gram-negative intact bacterial cells have been analysed by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) and shown to provide fingerprint mass spectra with discrete peaks being observed over the mass range from 3 to 40 kDa. The spectra show b

β¦ Synopsis
Adulteration by addition of bovine milk to water bu β alo milk employed for mozzarella cheese production is often observed. Water bu β alo milk and mozzarella cheese were analysed by matrix-assisted laser desorption/ionization mass spectrometry in order to achieve their rapid and accurate characterization and to evaluate possible fraudulence in mozzarella cheese production.

A number of potential matrix candidates were investigated with regard to the importance of the pH in the matrixassisted laser desorption/ionization mass spectrometry (MALDI/MS) analysis of non-covalently bound protein complexes. The matrices examined were 2,5-dihydroxybenzoic acid (DHB), 4-hydroxy-a
The role of peroxidase in the melanogenesis of 5-hydroxytryptamine was investigated by matrix-assisted laser desorption/ionization mass spectrometry. In order to establish the role of hydrogen peroxide in the reaction mixture, incubations were performed with peroxidase in the presence or absence of
