Digital Spatial Profiling
Digital spatial profiling (DSP) combines high-plex gene expression profiling with the spatial resolution of immunohistochemistry. This technology is a powerful tool for examining cellular interactions, tissue heterogeneity, pathogenicity, and response to therapy.
We are proud to be one of the first service providers to offer DSP utilizing the NanoString® GeoMx® Digital Spatial Profiler platform. This novel technology performs simultaneous, in situ spatial analysis of 570+ proteins and 18,000+ mRNAs from a single FFPE or frozen tissue section. You can select from a host of discovery-focused panels with the potential for customization, including the new, comprehensive IO Proteome Atlas (IPA) and Whole Transcriptome Atlas (WTA) panels. Together with our epigenetic and single-cell sequencing solutions, you have access to the most cutting-edge technologies available to study gene expression from every angle.
What is digital spatial profiling?
Digital spatial profiling (DSP) is a technique used to identify and quantify mRNA and protein expression in tissues such as FFPE (formalin-fixed paraffin-embedded) samples, fresh frozen tissue sections, tissue microarrays, and core needle biopsies.
Why is spatial profiling important?
Digital special profiling (DSP) is important for analyzing cellular heterogeneity and intracellular interactions, especially in the context of drug therapy response. Important advantages of DSP:
- Samples can be stored and probed again
- Multiple regions of interest (ROI) can be explored from a single FFPE slide
- DSP offers the benefits of both IHC/FISH and high-throughput expression analysis
MORPHOLOGICALLY-GUIDED GENE EXPRESSION PROFILING
Azenta’s digital spatial profiling service on the GeoMx platform enables morphologically-guided gene expression profiling of FFPE or fresh frozen tissues using one of NanoString’s expertly-curated, predesigned panels. Researchers can provide tissue blocks or slides for processing, or Azenta can leverage its network of biobank partners to source high-quality, consented samples on your behalf.
1. Stain Sections
Tissue is stained using a protein or mRNA panel and immunofluorescent markers
2. Define Target Areas
Regions of interest (ROIs) are selected using the GeoMx software (see FAQs)
3. Photocleave Barcodes
Barcodes are cleaved using UV light and captured
4. Separate ROIs
Barcodes from each ROI are deposited in separate tubes
5. Analyze Spatial Expression
ROI-specific barcodes are quantified to create expression profiles
