Single-cell Transcriptome Smart-seq Services

Single-cell Transcriptome Smart-seq Services

Single-cell transcriptome sequencing explores gene regulatory networks on a genome-wide scale, especially for stem cells, tumor cells, and early embryonic developmental cell populations of high heterogeneity. Single-cell transcriptome analysis provides insight into cell differentiation, cell reprogramming, and transdifferentiation processes associated with the gene regulatory networks.

CD Genomics provides single-cell transcriptome sequencing services based on the 10x Genomics and Smart-Seq2 technology platforms. Every step has been carefully designed and scientifically optimized to ensure high-quality research results, covering material selection, library construction, sequencing, and data analysis.

Smart-seq2 single-cell transcriptome sequencing services utilize the SMART amplification technology to reversely transcribe and amplify through PCR for mRNA in single cells, combined with transposase library construction technology and high-throughput sequencing to quantify gene expression, functional enrichment, and metabolic pathways in single cells. Moreover, the Smart-seq2 single-cell transcriptome sequencing technique can be applied to samples with low volume or cell heterogeneity, which has become an emerging tool in the study of early embryonic development, stem cells, cancer, immunity, and other research fields. As a result, this powerful tool for studying gene expression at the single-cell level greatly expands the application of RNA-Seq.

Advantages of SMART-seq Technology

Low initial volume: suitable for samples that cannot meet volume requirements of platforms such as 10X Genomics

High coverage: sequencing covers the full-length sequence of cDNA, enabling the expression of tens of thousands of genes per cell

Comprehensive information: in addition to gene expression, the data can be used for variable splicing, cSNP analysis, and lncRNA studies with poly-A structures

Not strand-specific

Bioinformatics Analysis

Standard analysis (reference gene sequence, reference genome sequence and gene annotation results are required) Advanced Analysis
1. Sequencing quality assessment and raw data filtering to remove adapter sequences and low-quality reads
