PacBio (Pacific Biosciences) sequencing, also known as Single Molecule Real-Time (SMRT) sequencing, is a third-generation DNA sequencing technology that allows for long-read sequencing of genomic DNA. It provides highly accurate, continuous reads with the ability to resolve complex regions of genomes, structural variants, and epigenetic modifications in a single run, making it valuable for applications in genomics, transcriptomics, and epigenetics.
Key Features
- Long read lengths averaging up to 15-20 kilobases or more
- High consensus accuracy (up to 99.9%) after correction
- Real-time sequencing providing immediate data output
- Ability to detect DNA modifications such as methylation without additional processing
- Minimal sequence bias with uniform coverage across the genome
- Suitable for de novo genome assembly and complex structural variation analysis
Pros
- Provides very long reads which assist in assembling complex genomes
- Capable of directly detecting epigenetic modifications
- High accuracy after consensus correction improves reliability of data
- Suitable for a wide range of applications including de novo sequencing and structural variation detection
- Reduces the need for supplementary technologies for certain analyses
Cons
- Relatively high cost per run compared to short-read sequencing methods
- Lower throughput compared to some other next-generation sequencing platforms
- Requires significant input DNA material which can be challenging with limited samples
- Analysis and data processing can be computationally intensive
