Molecular changes originate at the cellular level and solution-based techniques lack sensitivity to capture changes produced from small cell populations.
MALDI Imaging of sample cohorts along with SCiLS™ Lab analytical software extracts unique spatial patterns of proteins, lipids or metabolites and correlates them with sample pathology to identify and map putative biomarker ions.
Analyze large sample cohorts for biomarker discovery using molecular profiles and sample metadata to find relevant biomarkers that compliment histology. SCiLS™ Lab is the leading biomarker discovery software for analyzing mass spectrometry imaging with 2D and 3D visualization, as well as sophisticated statistical analysis with just a few mouse clicks, including: automatic spatial segmentation, co-localization analysis, classification model calculation, ROC and component analysis (PCA,pLSA etc).
Biomarker discovery protocols can accommodate fresh-frozen or formalin-fixed and paraffin embedded (FFPE) tissues or tissue microarrays (TMAs). Many tissue banks routinely fix biological specimens for long-term storage. Fixation agents act by crosslinking proteins into an insoluble Network, creating an excellent preservation technique. FFPE protocols involve additional processing steps of antigen-retrieval and protein digestion. Numerous publications have demonstrated the utiilty of imaging tryptic peptides from tissue or liberated N-linked glycans.

Bruker Daltonics IntelliSlides® now support a brand new workflow which allows for fast, simple, and highly automated set-up of Imaging acquisitions using flexImaging 6.0 and COMPASS for flex 2.1.
Using the TissueScout to scan barcoded IntelliSlides® allows for fast recognition of the correct sample image in flexImaging as well as alignment of the sample with instrument optics. The new workflow includes checks to confirm instrument performance, and automatic assignment of measurement regions using dedicated algorithms for whole tissue sections and Tissue microarrays (TMAs).
MALDI Imaging is made simple with Bruker Daltonics.
