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

Glycosylation characterization of therapeutic mAbs by top-and middle-down mass spectrometry

Rational selection of the optimum MALDI matrix for top-down proteomics by in-source decay.

Kevin Demeure et al.

Analytical chemistry, 79(22), 8678-8685 (2007-10-18)

In-source decay (ISD) in MALDI leads to c- and z-fragment ion series enhanced by hydrogen radical donors and is a useful method for sequencing purified peptides and proteins. Until now, most efforts to improve methods using ISD concerned instrumental optimization.

Use of 1,5-diaminonaphthalene to combine matrix-assisted laser desorption/ionization in-source decay fragmentation with hydrogen/deuterium exchange.

Pascale Lemaire et al.

Rapid communications in mass spectrometry : RCM, 27(16), 1837-1846 (2013-07-17)

In-Source Decay (ISD) in Matrix-Assisted Laser Desorption/Ionization (MALDI) mass spectrometry is a fast and easy top-down activation method. Our objective is to find a suitable matrix to locate the deuterons following in-solution hydrogen/deuterium exchange (HDX). This matrix must circumvent the
