CD Genomics provides robust transcriptome research service down to single-cell input levels in high-quality samples These global gene expression patterns in single cells already have dramatically advanced cell biology.

The Introduction of RNA Single-cell Sequencing

Cells are the basic unit of life and each cell is unique. The ability to reveal complex cellular events in biological systems is critical to a better understanding of cellular contributions during development or in disease progression. Gene expression research at the single-cell resolution on samples composed of mixed cell populations allows for deep insight into c into the transcriptome complexity of diverse cell types.

CD genomics offers best-in-class tools for library preparation and sequencing from a single cell, a few cells, and ultra-low inputs of RNA. Combining the robust cDNA synthesis technology with Illumina next-generation sequencing and analysis technologies, we offer reliable data of the highest quality to study cell-to-cell transcriptome heterogeneity

Single-cell Sequencing Workflow

The advent of cell sorting/partitioning technologies, such as flow cytometry and microfluidics, has made it possible to capture single cells, and the DNA or RNA of single cells were amplified to single-cell sequencing. The general workflow for single-cell sequencing is outlined below.

SNP Microarray

Techniques Description

Fluidigm C1 Single-Cell mRNA Workflow. With Fluidigm C1 system, We provide single-cell transcriptome profiling service at an optional scale. C1 can rapidly and reliably capture and process individual cells. The steps in Integrated C1 Single-Cell mRNA Seq workflow include fluidics circuits (IFCs) to capture cells, convert polyA+ RNA into full-length cDNA, and perform universal amplification of the cDNA. With the customizable microfluidic circuits, C1 enables seamlessly transition from identifying critical cell populations to generate sequencing libraries for transcript 3′ End Counting, full-length mRNA sequencing, DNA sequencing, epigenetic analysis, micro-RNA expression profiling and more.

SMART-seq Ultra Low Input RNA for sequencing. The SMART technology provides full-length transcript information, enabling analysis of transcript isoforms, gene fusions, point mutations, etc. The kit employing this technology enables users to perform cDNA synthesis directly from 1–1,000 intact cells or ultra-low input total RNA with high reproducibility and accurate representation of GC-rich transcripts. Full-length cDNA libraries produced with this kit are compatible with Illumina platforms.
