JapaneseDigital 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 and every level.
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
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.

Webinar Series | Advancing Transcriptomics: Gene Expression Screening, Single-Cell RNA-Seq, and Beyond
With this two-part webinar series, go beyond traditional transcriptomics and learn about the various NGS approaches available for gene expression analysis. In part 1, we take an in-depth look at various gene expression approaches, including RNA-Seq, single-cell RNA-Seq, digital spatial profiling, and more. In part 2, we explore the data generated from these approaches and how they can complement each other and confirm findings.
