Investigation of histological sections provides insight into disease processes. This is critical to researchers serving clinical research communities. Traditional approaches to pathological examination using staining and visual inspection are effective, but time-consuming and subjective. There exists an urgent need to augment manual pathological examination with cellular-level chemical information, to improve efficiency and accuracy of these diagnoses, and to gain a better understanding of the biochemical pathways that contribute to disease. Direct analysis of histopathological tissue sections using imaging mass spectrometry enables cancer biologists and other life science researchers to develop this type of information.

Protea's Mass Spectrometry Imaging Center performs histopathological studies using high resolution imaging mass spectrometry to provide chemical confirmation. Imaging mass spectrometry enables researchers to identify biomolecules that are indicative of disease and spatially localize them within the tissue. The LAESI DP-1000 System provides direct tissue analysis without sample preparation, and our custom imaging software, ProteaPlot, quickly and easily generates biomolecule distribution ion maps.


Protea's REDIchip™ enables matrix-free small molecule analysis on your MALDI platform.
