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.

Ultra-low-input and single-cell RNA sequencing (scRNA-Seq) methods enable researchers to explore the distinct biology of individual cells in complex tissues and understand cellular subpopulation responses to environmental cues. The variation between individual cells can be immense, even when examining the same cellular subpopulation. This is especially true of the transcriptome, which is a more reactive and dynamic -ome compared to the relative stability of the genome and epigenome. Highly sensitive scRNA-Seq approaches enhance the study of cell function and heterogeneity in time-dependent processes such as differentiation, proliferation, and tumorigenesis.

Advantages of single-cell RNA-Seq

Single-cell and ultra-low-input RNA-Seq methods are powerful tools for studying the transcriptome in an unbiased manner from minimal input. Single-cell RNA sequencing can be applied across a breadth of research areas, with the potential to transform our understanding of cellular function in health and disease. 

  • 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 and bulk RNA-Seq methods

High- and low-throughput scRNA-Seq methods

Single-cell RNA 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 scRNA-Seq methods utilize proven Illumina sequencing by synthesis (SBS) chemistry.

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 unique molecular identifier (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
