HiFi Sequencing – Unlock Your Next Great Discovery
With HiFi Sequencing you get the benefits of short reads and traditional long reads in one easy-to-use technology. Watch this short video to learn how HiFi Sequencing is empowering scientists to strive for new breakthroughs.
Explore A New Paradigm in Sequencing with HiFi Reads
Advanced scientific discoveries require sequencing data that is both accurate and complete. Single Molecule, Real-Time (SMRT) Sequencing technology has evolved to a different type of long read, known as highly accurate long reads, or HiFi reads.
PacBio is the only sequencing technology to offer HiFi reads that provide accuracy of >99.9%, on par with short reads and Sanger sequencing. With HiFi reads you no longer have to compromise long read lengths for high accuracy sequencing to address your toughest biological questions.
What are HiFi Reads?
HiFi reads are a type of data produced using the circular consensus sequencing (CCS) mode on one of the PacBio Sequel Systems. HiFi reads provide base-level resolution with >99.9% single-molecule read accuracy.
||HiFi reads can be used across a wide range of SMRT Sequencing applications, from whole genome sequencing for de novo assembly, comprehensive variant detection, RNA sequencing and more.|
How are HiFi Reads Generated?
How are HiFi Reads Different from Traditional PacBio Long Reads?
HiFi reads are produced by calling consensus from subreads generated by multiple passes of the enzyme around a circularized template. This results in a HiFi read that is both long and accurate. In contrast, traditional PacBio long reads are generated by a single pass of the enzyme around a circularized template, which although allows for overall longer read lengths, does not provide the high accuracy characteristic of HiFi reads. Learn more about how SMRT Sequencing works.
How Does HiFi Sequencing Compare with Other Technologies?
HiFi reads let you accurately detect all types of variants, from single nucleotide to structural variants, with high precision and recall and phase haplotypes, even in hard-to-sequence regions of the genome. Explore the resources below for more information on how HiFi reads perform relative to other technologies.

HiFi reads make understanding the accuracy of your sequencing data easy and straight forward, but there is a lot to know about accuracy when considering a sequencing technology.
In the precisionFDA Truth Challenge V2, which evaluated methods for variant calling in human genomes, approaches that use HiFi reads delivered the highest precision and recall in all categories.
What are the Benefits of HiFi Sequencing?
There are many advantage to using HiFi sequencing beyond the long read lengths and high accuracy. These include easy library preparation, low coverage requirements, small file sizes, and the fastest time to assembly. Explore the resources below better understand these advantages.
