Long-Read Sequencing

See what's possible with third generation sequencing technologies. With long-read sequencing, it's easier than ever to access large, complex DNA and RNA regions. 

Let's Talk

What Is Long-Read Sequencing Technology?

Long-read sequencing involves the sequencing of DNA or RNA molecules with extended read lengths, typically exceeding tens of thousands base pairs.


PacBio's long-read technology uses a single DNA molecule, thousands of nucleotides long, to produce individual DNA or RNA reads up to 20,000 bases. This can include information about epigenetic modifications — without extra bioinformatics steps.


Why Is Long-Read Sequencing Important?


Extended read length allows researchers to capture complex genomic regions, characterize structural variations, identify epigenetic modifications, and decode hard-to-sequence regions.


This can generate more accurate genome assemblies, better understanding of genetic variations, and enhanced insights into various biological processes. These benefits have applications from medicine to genomics research. 

What Can You Do?

Comprehensive Genome Assembly

Reconstruct or generate de novo genomes with fewer errors and areas of uncertainty, even in areas of high homology.

Haplotype Phasing

Obtain a complete and accurate representation of each copy of the genome or region of interest.

Variant Detection

Reach difficult to detect genomic regions, like high GC regions or large insertion-deletion areas. Link phenotypes to novel genes and causative variants.


Get methylation data from your sample without extra steps or protocols. Take simultaneous advantage of haplotype-phased and variant-called genomic information.
