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.

Spatial Proteogenomics

Simplify your multiomics studies with the multimodal Spatial Proteogenomics workflow. This workflow enables co-detection of RNA and protein from the same tissue slide on GeoMx® DSP with NGS as the readout method. Harness the sensitivity of both GeoMx RNA Assays and GeoMx Protein Assays to capture a complete picture of your biology starting with transcription to translation with capabilities to measure protein activation and post-translational modifications.

Immuno-Oncology and Immunology

The Immune Cell Profiling Core contains 18 targets for broad cell profiling of human samples (17 targets for mouse) and includes necessary controls for all GeoMx DSP experiments. Up to 6 10-plex modules plus 10 custom targets can be added to select the content most relevant to your human and mouse research.



The Neural Cell Profiling Core contains 20 targets designed for broad cell profiling of human samples (19 targets for mouse) and includes necessary controls for all GeoMx DSP experiments. Up to 6 10-plex modules plus 10 custom targets can be added to select the content most relevant to your human and mouse research.

GeoMx Protein Assays for NGS

Designed to profile 10’s-100’s of protein targets simultaneously with spatial resolution using NGS platforms and pipelines. Run the 4-plex GeoMx Protein Core for NGS, which includes necessary controls for GeoMx DSP experiments, with any selection of 10-plex modules.

Customize your GeoMx Protein Assays

As part of the overall Custom Protein Workflow, the GeoMx® Protein Barcoding Kit enables researchers to barcode antibodies of interest with a GeoMx DSP barcode in a single day with minimal hands-on time. Once antibodies have been barcoded, researchers can continue with their Custom Protein Workflow for any further appropriate functional testing. When custom antibodies are barcoded with the GeoMx Protein Barcoding kit, the addition of this content to GeoMx Protein Assays enables profiling up to 150 plex in a single experiment.

Neoadjuvant enoblituzumab in localized prostate cancer: a single-arm, phase 2 trial

B7 homolog 3 (B7-H3; CD276), a tumor-associated antigen and possible immune checkpoint, is highly expressed in prostate cancer (PCa) and is associated with early recurrence and metastasis. Enoblituzumab is a humanized, Fc-engineered, B7-H3-targeting antibody that mediates antibody-dependent cellular cytotoxicity.

New technologies to study helminth development and host-parasite interactions

How parasites develop and survive, and how they stimulate or modulate host immune responses are important in understanding disease pathology and for the design of new control strategies. Microarray analysis and bulk RNA sequencing have provided a wealth of data on gene expression as parasites develop through different life-cycle stages and on host cell responses to infection.

Digital spatial profiling of intraductal papillary mucinous neoplasms: Toward a molecular framework for risk stratification

The histopathologic heterogeneity of intraductal papillary mucinous neoplasms (IPMN) complicates the prediction of pancreatic ductal adenocarcinoma (PDAC) risk. Intratumoral regions of pancreaticobiliary (PB), intestinal (INT), and gastric foveolar (GF) epithelium may occur with either low-grade dysplasia (LGD) or high-grade dysplasia (HGD).
