Single-Cell and Ultra-Low-Input RNA-Seq
Introduction to single-cell RNA sequencing
Complex biological systems are determined by the coordinated functions of individual cells. Conventional methods that provide bulk genome or transcriptome data are unable to reveal the cellular heterogeneity that drives this complexity. Single-cell sequencing is a next-generation sequencing (NGS) method that examines the genomes or transcriptomes of individual cells, providing a high-resolution view of cell-to-cell variation.
Highly sensitive ultra-low-input and single-cell RNA sequencing (RNA-Seq) methods enable researchers to explore the distinct biology of individual cells in complex tissues and understand cellular subpopulation responses to environmental cues. These assays enhance the study of cell function and heterogeneity in time-dependent processes such as differentiation, proliferation, and tumorigenesis.
Advantages of single-cell RNA sequencing
Single-cell and ultra-low-input RNA-Seq are powerful tools for studying the transcriptome in an unbiased manner from minimal input.
- Robust transcriptome analysis down to single-cell input levels for high-quality samples
- Integrated protocol proceeds directly from whole cells and preserves sample integrity
- High resolution analysis enables discovery of cellular differences usually masked by bulk sampling methods
Single-cell sequencing and analysis workflow video
Single-cell sequencing can reveal the cell types present and how individual cells are contributing to the function of complex biological systems. See how you can use the Illumina workflow for single-cell sequencing, from tissue preparation through analysis.
High- and Low-Throughput Methods
Single-cell sequencing methods can be distinguished by cell throughput. Low-throughput methods include mechanical manipulation or cell sorting/partitioning technologies and are able to process dozens to a few hundred cells per experiment.
Other advances have enabled high-throughput single-cell profiling where researchers can examine hundreds to millions of cells per experiment in a cost-effective manner. Both the high- and low-throughput methods utilize Illumina sequencing by synthesis (SBS) chemistry, an industry-leading sequencing technology.

Low-Throughput Workflow for Ultra-Low-Input and Single-Cell RNA-Seq
The low-throughput method below is recommended for researchers who wish to process small numbers of cells for a particular study, such as dozens to a few hundred cells per experiment.
Single-cell RNA data analysis and insights
DRAGEN single-cell RNA Pipeline
The DRAGEN Single-Cell RNA (scRNA) Pipeline can process multiplexed single-cell RNA-Seq data sets from reads to a cell-by-gene UMI count gene expression matrix. The pipeline is compatible with library designs that have one read in a fragment match to a transcript and the other containing a cell-barcode and UMI. The pipeline includes the following functions:
- RNA-Seq (splice-aware) alignment and matching to annotated genes for the transcript reads
- Cell-barcode and UMI error correction for the barcode reads
- Genotype-based and genotype-free sample demultiplexing
- UMI counting per cell and gene to measure gene expression
- Cell hashing and feature counting by read 2 UMI
- Sparse gene expression matrix output
- Single cell RNA QC metrics
