PacBio's CiFi Method Dramatically Improves Genome Assembly Speed and Accuracy
Event summary
- PacBio and UC Davis researchers jointly developed CiFi, a new method for long-read 3C genome sequencing.
- CiFi integrates chromatin conformation capture (3C) with PacBio HiFi sequencing to generate chromosome-scale, haplotype-resolved genome assemblies from a single sequencing run.
- The method's capabilities were demonstrated with prairie and meadow vole genome assemblies, achieving scaffold N50 values exceeding 100 million base pairs.
- CiFi utilizes PacBio's Revio SPRQ chemistry to reduce the number of cells, libraries, and sequencing runs required for reference-quality genome assemblies.
The big picture
CiFi represents a significant advancement in genome sequencing, addressing limitations of existing Hi-C methods and lowering the barrier to entry for complex genomic projects. This innovation strengthens PacBio's position in the rapidly growing long-read sequencing market, which is crucial for advancements in personalized medicine, agricultural biotechnology, and fundamental biological research. The ability to generate high-quality assemblies with fewer resources could unlock new research avenues and accelerate scientific discovery.
What we're watching
