Allgemeine Beschreibung

MALDI-MS analyzes require highest purity matrices and reagents, as organic or trace metal contamination causes adverse effects during crystallization, ionization or measurement. Therefore, our portfolio of MALDI matrices and reagents such as 2′,4′,6′-Trihydroxyacetophenone monohydrate are designed to fulfill the demanding requirements of today′s challenging applications.

Anwendung

Verwendet in der MALDI-Analyse von sauren Glycanen und Glycopeptiden im Negativ-Ionen-Modus. Niedrigere Nachweisgrenze als 6-Aza-2-thiothimidin.

2′,4′,6′-Trihydroxyacetophenone monohydrate has been used as a matrix for oligosaccharide and glycopeptide analysis using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI/TOF).

Analysis of anthocyanins in red wine and fruit juice using MALDI-MS.

J Wang et al.

Journal of agricultural and food chemistry, 47(5), 2009-2015 (1999-12-20)

Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) is a powerful new technique that will have a great impact on food analysis. This study is the first to demonstrate the applicability of MALDI-MS to perform both qualitative and quantitative analyses of anthocyanins

Matrix-assisted laser desorption ionization time-of-flight mass spectrometry: a powerful tool for the mass and sequence analysis of natural and modified oligonucleotides.

U Pieles et al.

Nucleic acids research, 21(14), 3191-3196 (1993-07-11)

We report the analysis and characterization of natural and modified oligonucleotides by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS). The present technology was highly improved for this class of compounds by using a new matrix, 2,4,6-trihydroxy acetophenone, together

Analysis of acidic oligosaccharides and glycopeptides by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.

D I Papac et al.

Analytical chemistry, 68(18), 3215-3223 (1996-09-15)

2,5-Dihydroxybenzoic acid (DHB) is the most commonly used matrix for matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI/TOF) of oligosaccharides. Because acidic, sialylated oligosaccharides are detected at only the low picomole level with DHB, alternative matrices were screened to identify a

Synthesis and tau RNA binding evaluation of ametantrone-containing ligands.

Gerard Artigas et al.

The Journal of organic chemistry, 80(4), 2155-2164 (2015-01-21)

We describe the synthesis and characterization of ametantrone-containing RNA ligands based on the derivatization of this intercalator with two neamine moieties (Amt-Nea,Nea) or with one azaquinolone heterocycle and one neamine (Amt-Nea,Azq) as well as its combination with guanidinoneamine (Amt-NeaG4).
