In the same way that a GPS captures geographic coordinates within an area to create a map and locates where you are, spatial biology does the same on the tissue, cellular and molecular level. Through this technology, we can map the spatial architecture of a tissue sample and how cells interact with each other. Additionally, it enables researchers to see multicellular interactions that are not possible by sequencing or any other available technologies. The NanoString GeoMx® Digital Spatial Profiler (DSP) makes spatial transcriptomics and spatial proteomics possible by visualizing the spatial architecture of intact tissue sections and analyzing multiple biomarkers from a single sample. GeoMx® Digital Spatial Profiler Combining standard immunofluorescence techniques with digital optical barcoding technology, the GeoMx® Digital Spatial Profiler enables high plex, spatially resolved profiling of protein and RNA. The GeoMx Assays allow for imaging and profiling from a single FFPE or fresh frozen tissue section. Image Workflow Using the BOND RX fully automated research stainer from Leica cuts down on tedious hands-on time staining samples for GeoMx DSP, enabling translational research through batch analysis of large numbers of samples from multi-cohort studies. Benefits Quantify up to 100+ proteins and up to the whole transcriptome with spatial context Focus on rare cells or compartment-specific regions of interest in the tissue Preserve precious samples with non-destructive processing Work with FFPE or fresh frozen tissue Research Focus Tissue Atlasing Deeply profile transcriptomic and proteomic changes in different tissue structures within various organs in order to better understand organ function in health and disease. Image Image Biomarker Discovery and Validation Discover novel RNA or protein biomarkers that correlate with disease onset, progression, or therapeutic response and are found in specific tissue compartments. Validate these biomarkers in a larger sample set with cohort analysis. Immune Profiling Profile the phenotype and transcriptional changes occurring in the immune cell infiltrate within tissues in response to various disease such as cancer, organ rejection, and viral/bacterial infections. Image Biology-Driven Profiling: Region of Interest Selection Strategies Segmentation: Identify and profile distinct biological compartments within a region of interest (ROI). Image A 5 μm section of kidney depicts the proximal convoluted tubule. This section has been segment profiled guided by CD10 and CD31 morphology marker staining. Geometric Profiling: Profile with any geometric shape to characterize distinct tissue regions. Image The Islet of Langherans is geometrically profiled with Insulin, glucagon and PanCK morphology markers. Evaluate how proximity around a central structure affects biological response with radiating ROIs. Image The invasive margins of two colorectal tumor samples are analyzed using contour segments extending into the tumor and outside the tumor into the stroma and profiled with 1400+ RNA probes with NGS read out.
