Single-Cell Full-Length Transcriptome Sequencing

Single-cell full-length transcriptome sequencing (RNA-seq) is a technology that uses the 10x Genomics Chromium (10x) platform to obtain single-cell cDNA and combine it with transcriptome analysis on a long-sequence sequencing platform. This method combines the advantages of full-length transcriptome and single-cell sequencing, providing a powerful tool for discovering and quantifying isoforms, analyzing alternative splicing at the single-cell level.

Overview of Single-Cell RNA-Seq with Long-Read Sequencing

Single-cell RNA sequencing (scRNA-seq) has made up for the limitations of bulk RNA sequencing (RNA-seq). This method can resolve gene expression profiles in single cells for more accurate transcriptome assessment, and is currently receiving widespread attention and application. There are two main characteristics of the single-cell experiments, including the barcoding of cDNA synthesized by each cell with cell-specific barcodes and of individual mRNA molecules with unique molecular identifiers (UMIs). Among them, the former method allows better quantification of transcripts at the single-cell level. Since UMIs are usually degraded, it requires the high accuracy of the sequencing platform. ScRNA-seq is now a widely adopted approach for profiling transcriptomic heterogeneity. However, assessing transcript-level changes between cell types using current scRNA-seq protocols remains challenging, as they rely on short-read sequencing. Nowadays, long-read sequencing technology is widely used in scRNA-seq to generate complete transcript information in a single cell, overcoming the fundamental limitations of short-read sequencing.
