How NanoString's 3D Technology Is Revolutionizing Cellular Research
Imagine trying to understand a complex movie by watching only every tenth frame—this is the challenge scientists have faced when studying biological systems by analyzing DNA, RNA, or proteins in isolation.
Traditional methods have provided valuable but fragmented insights, much like trying to appreciate a symphony by hearing only the string section.
The introduction of NanoString's 3D Biology™ platform has changed this paradigm entirely, enabling researchers to simultaneously analyze these three critical dimensions of biological information from minute samples.
This revolutionary approach, particularly its capability for "simultaneous digital counting of DNA, RNA and protein" as highlighted in Abstract 2441, represents a significant leap forward in our ability to understand the intricate workings of cells in health and disease.
NanoString's 3D Biology™ represents a novel category of life science tools that enable the simultaneous analysis of DNA, RNA, and proteins from remarkably small amounts of sample—as few as 150,000 cells according to early applications .
"Our customers will benefit from multiplexed, single molecule, digital quantification of proteins with a rapidly expanding menu of assays"
At the core of NanoString's system is its unique molecular barcoding technology that uses color-coded probes to identify specific nucleic acids and proteins 2 .
The first concrete implementation of the 3D Biology concept was the RNA:Protein Immune Profiling Panel launched in September 2015 . This pioneering assay enabled researchers to simultaneously analyze 770 RNA targets and 30 protein targets in as few as 150,000 cells—an unprecedented capability at the time .

| Cell Surface Proteins | 30 | Digital Count | Protein abundance and cellular markers |
| Combined Analysis | 800+ | Integrated Profile | Pathway activity and regulatory mechanisms |
"The high-plex protein assay makes the CosMx SMI a true multiomic solution"
The nCounter® Analysis System serves as the foundation for 3D Biology experiments. This platform offers a cost-effective way to profile hundreds of molecular targets simultaneously with high sensitivity and precision .
| Component | Function | Significance |
|---|---|---|
| Color-coded Molecular Barcodes | Hybridize directly to target nucleic acids and proteins | Enable multiplexed detection without amplification |
| Highly Validated Antibodies (from CST) | Recognize and bind specific protein targets | Ensure accurate protein quantification |
| Customizable Assay Panels | Simultaneously measure DNA, RNA, and protein targets | Allow researchers to tailor experiments to specific questions |
| Integrated Analysis Software | Interpret complex multi-dimensional data | Transform raw counts into biological insights |
The ability to simultaneously analyze DNA, RNA, and proteins has far-reaching implications across biological research and clinical applications. As Dr. Grant Kolar of St. Louis University noted regarding related NanoString technologies, such tools become "integral to our laboratory's future direction" 1 .
Enables a more comprehensive understanding of tumor biology and the immune response.
Supports development of diagnostic tests like the FDA-cleared Prosigna® Breast Cancer Assay .
Accelerates discovery and validation of therapeutic targets.
Introduction of nCounter Analysis System - Enabled multiplexed gene expression analysis
Launch of RNA:Protein Immune Profiling Panel - First commercial 3D Biology product
Partnership with Cell Signaling Technology - Expanded protein assay capabilities
Integration with spatial biology platforms - Added spatial context to multi-omic data
"It allowed us to visualize single-cell reference maps directly in organs. The scale of 1000-plex gene panel with image-guided cell segmentation makes the CosMx SMI, a unique platform for spatial genomics!"
NanoString's 3D Biology technology, with its capacity for simultaneous digital counting of DNA, RNA, and protein, represents a fundamental shift in how we approach biological research. By breaking down the traditional silos between molecular analysis types, this platform provides a more holistic understanding of the complex machinery of life.
As the technology continues to evolve and integrate with complementary approaches like spatial biology, its impact on both basic research and clinical applications is likely to grow. From accelerating drug development to enabling more precise diagnostic and prognostic tools, 3D Biology brings us closer to a comprehensive understanding of disease mechanisms and treatment opportunities.
