Precision Immuno-oncology: SPATIAL PROFILING OF RNA OR PROTEIN TARGETS ON A SINGLE TISSUE SECTION

Gain deeper understanding of the tumour and tumour microenvironment with multiplex gene expression and protein analysis from distinct regions of interest from a whole slide section.

With key applications in immune-oncology and neuroscience research, this highly multiplexed assay can detect and measure up to 800 analytes in a single section.

- Highly multiplexed RNA or protein detection - up to 800 targets in a single run

- RNA or protein analysis from a single FFPE section

- Morphological context - whole slide 4 colour imaging to guide profiling and ROI selection

- Maintains sample integrity - samples can be reused

- Digital quantitation - up to 6 logs (base 10) dynamic range

- High resolution - from 600 micron regions of interest down to single-cell analysis

- High throughput: up to 20 sections per day

 

Data output

Each region of interest is analysed on the nCounter platform providing counts for each individual analyte. Once all regions of interest have been analysed, raw data can be provided in an excel document along with normalised data in graphical form including heatmaps to provide increased data insights.

Raw data is provided in the form of an excel data sheet, and images include whole tissue images at low magnification and individual ROI at high magnification from all samples. Power point documentation and DSP App (a live data visualization tool) will be provided to customers.

 

Simple and rapid workflow

DSP technology builds upon the highly robust nCounter digital barcoding technology from Nanostring. A simple and fast workflow delivers accurate, reproduceable results for immuno-oncology research.

Precision analysis of any tissue region from whole tissue to single cell

Up to 4 morphology fluorescent markers can guide selection of regions of interest. Versatile regions of interest from whole tissue, geometric areas or single cell regions can be selected.

Data Quality Control

The use of 6 positive and negative control probes ensure hybridisation efficiency, prep station purification and imaging are at optimum levels. Assay variation is controlled and monitored using control targets built into the CodeSet reagents. 

High reproducibility and correlation of Positive Control Counts vs. protein tag set concentration. Nanostring assays provide a correlation of positive control counts to Protein tag target concentration with R2>0.95.
