GeoMx® Protein Assays
Helping Your Research
High-plex Spatial Proteomic Analysis
GeoMx Protein Assays enable quantitative, spatial analysis of 96+ proteins from a single FFPE or Fresh Frozen slide, vastly expanding the number of markers you can profile from a single tissue section compared to traditional immunohistochemical methods. All assays are validated for use in multiplex so you can focus on the biology of interest without wasting time troubleshooting assay performance.
How it Works
The assay relies upon antibodies coupled to photocleavable oligonucleotide tags designed for readout with nCounter® (≤96-plex) or NGS (over 100-plex) platforms. After hybridization of antibodies to slide-mounted tissue sections, the oligonucleotide tags are released from discrete regions of the tissue via UV exposure. Released tags are counted in a standard nCounter assay or sequenced using NGS, and counts are mapped back to tissue location yielding a spatially resolved digital profile of protein abundance.
All GeoMx® Protein Assays undergo extensive validation to ensure high quality GeoMx DSP data. Read more about GeoMx Antibody Validation in this white paper.

Breast cancer is a heterogenous disease with variability in tumor cells and in the surrounding tumor microenvironment (TME). Understanding the molecular diversity in breast cancer is critical for improving prediction of therapeutic response and prognostication.

Immune responses to cancer are highly variable, with mismatch repair-deficient (MMRd) tumors exhibiting more anti-tumor immunity than mismatch repair-proficient (MMRp) tumors. To understand the rules governing these varied responses, we transcriptionally profiled 371,223 cells from colorectal tumors and adjacent normal tissues of 28 MMRp and 34 MMRd individuals.
