Breaking new ground in spatial imaging, the NanoString CosMx provides high-plex in-situ analysis at cellular and subcellular resolution in FFPE and fresh frozen tissue.
The CosMx uses automated fluidics and imaging to hybridise and visualise 16 sets of four fluoresecent reporters, enabling protein imaging of 64 different antibodies
Our experience across a range of platforms for spatial biology allows us to recommend the most appropriate platform for each research project.
We understand the strengths and limitations of each platform – and how to get the best out of them.
We take care of the complete process from sample preparation to data analysis, with robust QA procedures and complete traceability of your precious samples.
Analysis of mRNA expression profile with spatial context at the level of a single cell is known as single-cell spatial transcriptomics. Each cell has a unique transcriptomic fingerprint as gene expression patterns can be heterogeneous even amongst similar cells in both standard and abnormal cell states.
GeoMx resolves cell population-level expression of RNA and protein with spatial context and can enrich for populations using highly configurable tools. GeoMx can be used to investigate up to the whole transcriptome 18,000+ targets and >100 antibodies on the same slide.
CosMx resolves RNA and protein expression at single molecule, subcellular resolution in situ. CosMx delivers ultra high-plex technology to quantify up to 1,000 RNA and 64 protein targets at single-cell resolution. This enables cell typing and pathway analysis to resolve cell state, cell function, cell-cell interactions and highly informative cell signalling.
CosMx spatial analysis can be performed on both FFPE and fresh frozen tissue, although at Propath we accept tissue in any form, including wet tissue in formalin/ethanol for processing.
To provide additional context, we often take additional sections for H&E, RNAscope to test RNA reactivity or IHC overlays.
The smallest area that can be imaged on a single slide is 16mm2 (equivalent to 62 Fields of View). The largest is 300m2 (equivalent to 1,158 Fields of View).
Within this range, areas of 50mm2, 100 mm2 and 200 mm2 can also be imaged.
The CosMx can accommodate up to 4 slides in a single run. Throughput depends on the size of the area being imaged and the number of analytes being measured.
As examples, to image an area of 50mm2 (equivalent to 193 FOVs) on each of 4 slides:
- using the 1,000 plex RNA panel would take approximately 7 days
- using the 64 plex protein panel would take approximately 5 days
Both are in addition to the time required for study set up, sample prep, QC, QA and data analysis.
Custom Protein panels are not yet available; however the CosMx Human Immuno-oncology Protein panel is a 64-plex assay providing a comprehensive coverage of protein expression for tumour and immune responses.
Currently, RNA panels are either 100-plex or 1,000-plex; the first is fully customisable whilst the second can accommodate a maximum of 350 custom targets.
Propath offers various modules of data analysis for CosMx datasets, ranging from basic to advanced analysis in AtoMx, a cloud-based spatial biology analysis platform. Propath can also offer access to AtoMx for analysis and visualisation of CosMx data.
