MALDI Imaging - Direct imaging of proteins, peptides, lipids, drugs and metabolites in tissue

MALDI Imaging allows direct label-free measurement of proteins, peptides, lipids, drugs, and metabolites from tissue. The distribution of the detected compounds can be visualized as images which can be integrated with other imaging modalities to study the molecular signatures of tissue compartments.

Defining a new type of molecular histology

The histological context of a molecular measurement is crucial for the correct interpretation of molecular imaging data. Conventional histological staining can be performed on the same tissue section. Bruker’s unique software can overlay a high resolution virtual microscopy slide with the molecular image. This effectively turns MALDI Imaging into standard histology with an added molecular dimension.

Location and quantitation of drug and metabolites

MALDI Imaging allows the measurement of drug distribution in tissue. Furthermore it allows the molecular differentiation of the parent drug and metabolites. The combination of MALDI Imaging with the histology gives additional insight and allows to bridge biology and chemistry in drug development.

Discovering new biomarkers of disease

Cancer samples often are highly heterogenous with a lot of different histological structures on a rather small scale. Since MALDI Imaging preserves the spatial distribution and the histology of the samples, it is perfectly suited for the analysis of human cancer samples. MALDI Imaging has been successfully applied to the detection of previously unknown proteins in cancer. Moreover, molecular signals or patterns have been shown to correlate with tumor subtypes or other parameters such as outcome or susceptibility to treatment.  

Other application areas of MALDI Imaging

Other application areas of MALDI Imaging include model studies in neuroscience, developmental biology, molecular interactions of bacterial colonies, plant metabolism and others.
