A vast resource of biological insight is stored in hospital archives and research biobanks worldwide: Formalin-Fixed Paraffin-Embedded (FFPE) tissue samples. For researchers in translational medicine, these archival specimens are irreplaceable, often linked to long-term patient records. However, unlocking their molecular secrets with spatial context has been a persistent technical hurdle. This is the specific challenge our FFPE transcriptomics solution is designed to meet. At STOmics, we created the STOmics OMNI platform to transform these preserved tissue blocks into detailed spatial molecular maps. The STOmics OMNI system provides a dedicated path to analyze archival samples with the precision modern discovery requires.

Capturing More Molecular Information from Each Sample

The first barrier with archival FFPE samples is the perceived quality and quantity of recoverable RNA. Years of fixation can degrade nucleic acids, making efficient capture critical. Our enhanced STOmics OMNI V1.1 solution directly addresses this. It is engineered to achieve a higher capture efficiency for RNA molecules from these challenging samples. This capability means researchers can achieve richer RNA profiling from every experimental run. By obtaining more usable data per sample, the FFPE Transcriptomics Solution enables deeper biological insights, ensuring that precious, often limited, archival material yields the maximum possible scientific return.

Maintaining Precise Spatial Fidelity in the Analysis

Beyond simply capturing molecules, a true spatial solution must preserve their original location within the tissue architecture. A core innovation of the STOmics OMNI platform is its enhanced tissue diffusion control. This technical advancement is crucial for archival samples, as it retains true single-cell resolution during the analytical process. This means the molecular profile generated can be confidently assigned to its specific cellular origin, avoiding blurring between neighboring cells. Furthermore, this controlled process allows for sample multiplexing within a single run, increasing throughput without sacrificing the spatial accuracy that makes the data from an FFPE Transcriptomics Solution so valuable for understanding disease pathology.

Enhancing Data Utility for Confident Interpretation

Generating data is one step; producing reliable, interpretable information is another. The third pillar of the STOmics OMNI system focuses on transforming raw spatial data into actionable knowledge. The platform delivers improved data usability, with enhancements designed to efficiently handle the complexities of clinical samples. This leads to more straightforward and confident spatial data interpretation. Researchers can achieve precise spatial single-cell analysis, which allows for well-defined tissue annotation and stratification. Seeing clear cell-type boundaries and expression patterns within an FFPE sample turns historical tissue into a clear dataset for hypothesis testing and biomarker discovery.

The ability to interrogate archival FFPE samples with high-plex spatial technology opens new doors in disease research. It allows scientists to connect long-term clinical outcomes with deep molecular phenotyping, all within the original tissue context. The STOmics OMNI platform from STOmics is built specifically for this mission. Our FFPE Transcriptomics Solution provides the necessary tools—from optimized chemistry to analytical frameworks—to unlock the full spatial architecture of preserved samples. For teams working to extract future insights from the past, this focused solution offers a reliable path forward. STOmics is committed to ensuring these invaluable tissue resources can contribute fully to the progress of spatial biology.
