iso-seq / pacbio transcriptome sequencing introduction

rna sequencing has become the most frequently used method for the majority of researchers conducting gene expression profiling. however, it is difficult to obtain a complete picture of the transcriptome because short reads cannot accurately assemble complex transcripts.

isoform sequencing (iso-seq) developed by pacific biosciences (pacbio), is based on long-read sequencing technology. the unique long-read sequencing feature allows this method to identify new isoforms with extraordinary precision. the iso-seq application generates full-length cdna sequences — from the 5’ end of transcripts to the poly-a tail — eliminating the need for transcriptome reconstruction using isoform-inference algorithms. the iso-seq method provides accurate information about alternatively spliced exons and transcriptional start sites. it also reveals information about poly-adenylation sites for transcripts across the full complement of isoforms within targeted genes or the entire transcriptome.
