Explore a new paradigm in sequencing with HiFi reads

Advanced scientific discoveries require sequencing data that is both accurate and complete. PacBio 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 compromise long read lengths for high accuracy sequencing to address your toughest biological questions.

  • 2HiFi yield specification based on HG002/GM24385 human DNA extracted with Nanobind CBB kit and prepared with SMRTbell prep kit 3.0.
  • 3Run time specification is for the sequencing reaction.
  • 5HiFi yield is dependent on library fragment size. Yield is typically lower for shorter libraries.
