Egg White as a quality control in MALDI Mass Spectrometry Imaging

ABSTRACT: Tryptic peptides and N-glycans were spatially mapped and visualised on formalin-fixed paraffin-embedded (FFPE) endometrial cancer tissue microarrays (TMAs) using an ultrafleXtreme MALDI-ToF/ToF MS instrument (Bruker Daltonics). FFPE egg white was placed either side of each TMA and used as an external control to monitor detector performance and sample preparation.

The strength of MALDI-MSI is to analyze and visualize spatial intensities of molecular features from an intact tissue. The distribution of the intensities can then be visualized within a single tissue section or compared in between sections, acquired consecutively. This method can be reliably used to reveal physiological structures and has the potential to identify molecular details, which correlate with biological outcomes. MALDI-MSI implementation in clinical laboratories requires the ability  ...[more]
