Descrizione generale

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.

Applicazioni

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).
Used in MALDI analysis of acidic glycans and glyco­peptides in negative ion mode. Lower limit of detection than 6-aza-2-thiothimidine.

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

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
