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

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

Sublimation of new matrix candidates for high spatial resolution imaging mass spectrometry of lipids: enhanced information in both positive and negative polarities after 1,5-diaminonapthalene deposition.

Aurélien Thomas et al.

Analytical chemistry, 84(4), 2048-2054 (2012-01-17)

Matrix sublimation has demonstrated to be a powerful approach for high-resolution matrix-assisted laser desorption ionization (MALDI) imaging of lipids, providing very homogeneous solvent-free deposition. This work presents a comprehensive study aiming to evaluate current and novel matrix candidates for high

Rapid sequencing and disulfide mapping of peptides containing disulfide bonds by using 1,5-diaminonaphthalene as a reductive matrix.

Yuko Fukuyama et al.

Journal of mass spectrometry : JMS, 41(2), 191-201 (2005-12-31)

MS/MS is indispensable for the amino acid sequencing of peptides. However, its use is limited for peptides containing disulfide bonds. We have applied the reducing properties of 1,5-diaminonaphthalene (1,5-DAN) as a MALDI matrix to amino acid sequencing and disulfide bond
