Pacbio RNA Sequencing
Nowadays, short-read RNA sequencing (RNA-seq) is the most widely used high-throughput method and has greatly expanded our ability to study transcriptome complexity, such as predicting alternative splicing events. However, short-read RNA-seq has many inherent limitations and cannot accurately determine all isoforms. In addition, this traditional approach does not handle well non-model organisms that lack well-annotated genomes in terms of structure and function. Long-read RNA-seq can overcome some of the inherent limitations of short-read RNA-seq and improve gene prediction and annotation in genome assembly, ultimately providing full-length mRNA sequences and complete structural information.
Based on PacBio's Single Molecule, Real-Time (SMRT) Sequencing technology, the average read length can now reach 80 Kb, which is already longer than the length of typical genes in the general transcriptome. Therefore, using this long-read sequencing platform for transcriptome research, full-length transcript information can be obtained directly without assembly, thus ensuring the accuracy of transcriptome sequencing results to a greater extent.
Advantages of Long-Read RNA-Seq over Short-Read RNA-Seq
- PacBio's SMRT Sequencing and Iso-seq analysis allow generating full-length transcripts with no assembly required.
- Long-read RNA-seq performs better in genomic non-model organisms that lack good annotation.
- Overcome the problem of short splicing and incomplete information of transcripts in species without a reference genome.
- It can realize the investigation of structural variants such as alternative splicing and fusion genes with reference genomic species.
