Solution Overview

Stereo-seq OMNI V1.1 is a revolutionary sequencing-based spatial multi-omics solution specifically designed for Formalin-fixed and Paraffin-embedded (FFPE) samples.
It enables true single-cell level gene expression profiling combined with histology study, providing unparalleled insights for groundbreaking discoveries in biology and clinical translational research. Stereo-seq OMNI delivers best-in-class data and bioinformatics workflow for analyzing spatial whole-transcriptome information.

Product Highlight

Deeper Insights Per Run: Achieve 1X–3X Higher capture efficiency for richer RNA profiling and deeper biological insights from every run.

Preserved Spatial Fidelity: Enhanced tissue diffusion control retains true single-cell resolution while allowing for sample multiplexing.

Improved Data Usability: Enhanced data usability of over 100% (approximately 2X) to efficiently transform data into information within clinical samples.

True Single-Cell Profiling at Scale: Achieve precise spatial single-cell analysis for well-defined tissue annotation and stratification.

Stain and image

Carry out tissue fixation and stain the tissue using ssDNA dye (nuclei staining, fluorescence), or hematoxylin and eosin (H&E staining, bright field) to visualize the tissue under epi-fluorescence microscopes. An upright microscope is recommended for optimal image generation.

RNA capture & cDNA synthesis

To extract the total RNA from FFPE tissues, the tissue is permeabilized to release RNA from cells, allowing it to bind with random probes and generate cDNA in situ (Stereo-seq Chip N). Each cDNA synthesized at a specific spot (500nm resolution) is attached to its spatially barcoded probe, enabling the subsequent mapping of gene expression within a tissue section after sequencing.

Data analysis & visualization

Run your sequencing data on the Stereo-seq Analysis Workflow (SAW), which involves Linux command line-based pipelines, to map the sequenced reads back to their spatial locations on the tissue section, and then interactively display the results on StereoMap visualization software, a Windows/MacOS compatible desktop application.
