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.

GeoMx RNA Assay: High Multiplex, Digital, Spatial Analysis of RNA in FFPE Tissue.
RNA in situ hybridization (ISH) is a widely used technique for the localization of mRNA in tissues. Limitations to traditional ISH include the number of targets that can be analyzed concurrently and the ability for many of these assays to be used in formalin-fixed, paraffin-embedded tissues (FFPE).
