    Long-read Single-Cell Transcriptome Sequencing


    Introduction


    Long-read single-cell transcriptome sequencing refers to the use of Nanopore sequencing technology to directly read the full-length cDNA reverse transcribed from single cells processed by 10x Genomics. This process enables the identification and quantification of isoforms within individual cells, as well as the detection of alternative splicing events at the single-cell level. By combining the advantages of single-cell analysis with third-generation long-read sequencing techniques, long-read single-cell transcriptome sequencing elevates single-cell transcriptomic analysis from the gene level to the isoform level.
