Single-cell RNA-seq · 10x Genomics Chromium technology

Single-Cell RNA-seq,
cell by cell

A tissue is not a uniform mass: it is thousands of different cells, each with its own identity and state. With 10x Genomics Chromium technology we read the transcriptome of each cell separately, and with deep learning we turn that map into answers: which cells are there, how they change and which ones matter for your question.

Why cell by cell

The average hides what matters most

When you measure a whole tissue you get the average of all its cells. If only a small population changes, that signal is diluted and disappears. Single-cell brings it back.

Bulk RNA-seq

One signal per sample

Fast and very useful for comparing conditions, but all cells are blended into a single value. Small populations and intermediate states stay hidden.

Single-cell RNA-seq

One signal per cell

Each cell is read separately and grouped with similar ones. Cell types, activation states and that rare population that explains your phenotype come to light.

The technology

10x Genomics Chromium: one droplet,
one cell, one barcode

The challenge of single-cell is reading thousands of cells at once without losing track of which cell each message came from. The 10x Genomics Chromium platform, the reference in the field, solves it with microdroplets.

Cells in suspension flow through a microfluidic chip that encloses them, one by one, in tiny droplets together with a gel bead. Each bead carries millions of copies of a unique cell barcode. Inside the droplet the cell is lysed and all its RNA is tagged with that barcode. Each molecule also receives a UMI, its own identifier, so we count real molecules and not copies. Everything is then sequenced together and the barcodes let us rebuild, cell by cell, which genes were active.

Each cell enters its own droplet with a bead that tags all its RNA with the same barcode. After sequencing, the barcode returns every message to its cell of origin.

Thousands of cells per sample

The chip encapsulates thousands of cells in minutes, enough to capture even populations that make up a tiny fraction of the tissue.

One barcode per cell

All the RNA from one cell shares the same barcode, so nothing gets mixed: every profile belongs to a specific cell.

Real molecules, not copies

The UMI tells each original molecule apart from its amplification copies, so the expression we measure is the real one.

Modalities

The right chemistry for every question

10x Genomics offers several chemistries on the same platform. We choose with you the one that best fits your sample and what you want to discover.

The starting point

Universal 3' Gene Expression

The standard for characterizing cell types and states and comparing conditions at single-cell resolution.

Immunology

Universal 5' + immune profiling

Gene expression and, in the same cell, the sequence of T and B cell receptors (TCR/BCR) to study clonality and immune response.

Fixed and FFPE samples

Flex

Works with fixed cells and even paraffin-embedded samples. Lets you collect samples at different times and process them together, and scale up to very large studies.

Regulation

Multiome (ATAC + expression)

Chromatin accessibility and gene expression from the same cell: not only which genes switch on, but which regulatory regions allow it.

Protein + RNA

Cell surface proteins

Adds surface markers with tagged antibodies to read RNA and protein at the same time and sharpen the identity of each cell.

Frozen tissue

Single-nucleus RNA-seq

When live cells cannot be obtained, for example in frozen tissue, brain or biobanks, we read the cell nuclei.

The sample

A good single-cell study starts before sequencing

In single-cell, sample quality decides almost everything. We support you from collection so it arrives in the best possible condition.

Artificial intelligence

Deep learning that matches your data

A single-cell experiment generates millions of data points, very sparse and full of technical noise. Classic linear methods fall short, so we use deep learning models that learn the real statistical structure of your cells.

What you receive

An atlas of your cells, ready to use

  • Annotated cell atlas

    All your cells grouped and identified by type and state, with their markers.

  • What changes in each cell type

    Proportions and genes that change between conditions, population by population.

  • Trajectories and cell communication

    How cells transition between states and which signals they exchange.

  • Figures and interpreted report

    Cell maps, dot plots and heatmaps ready to publish, with a report explaining what they mean.

Intusomics® Explorer

Explore your atlas whenever you want, no coding needed: color the map by any gene, compare populations and build your own interactive plots from your private area.
