The double nature of 1,5-diaminonaphthalene as matrix-assisted laser desorption/ionization matrix: some experimental evidence of the protonation and reduction mechanisms.

Laura Molin et al.

Rapid communications in mass spectrometry : RCM, 25(20), 3091-3096 (2011-09-29)

1,5-Diaminonaphthalene (DAN) has been described as an interesting and effective matrix for matrix-assisted laser desorption/ionization (MALDI) experiments in positive ion mode, being able to activate in-source decomposition phenomena and, when employed for the analysis of proteins containing disulphide bridge(s), being

Matrix precoated targets for direct lipid analysis and imaging of tissue.

Junhai Yang et al.

Analytical chemistry, 85(5), 2907-2912 (2013-02-20)

We have developed targets precoated with matrix for imaging lipids in tissues using matrix-assisted laser desorption ionization mass spectrometry (MALDI MS). Thin tissue sections (rat kidney and mouse or rat brains) were placed onto 1,5-diaminonaphthalene precoated targets (prepared beforehand by

Mass spectrometric characterization of phosphorylated peptides using MALDI in-source decay via redox reactions.

Daiki Asakawa et al.

Journal of mass spectrometry : JMS, 47(2), 180-187 (2012-02-24)

Matrix-assisted laser desorption/ionization in-source decay (MALDI-ISD) has been used for characterization of a phosphorylated peptides and proteins because labile phosphate group is not lost during the MALDI-ISD process. The conventional MALDI-ISD is initiated by the hydrogen transfer from reducing matrix

MALDI-in source decay applied to mass spectrometry imaging: a new tool for protein identification.

Delphine Debois et al.

Analytical chemistry, 82(10), 4036-4045 (2010-04-20)

Matrix-assisted laser desorption ionization-mass spectrometry (MALDI-MS) imaging is a powerful technique giving access to the distribution of a large range of biomolecules directly from a tissue section, allowing, for example, the discovery of new pathological biomarkers. Nevertheless, one main difficulty
