Delivering highly accurate long reads to drive discovery in life science
What is SMRT Sequencing?
Single Molecule, Real-Time (SMRT) Sequencing is the core technology powering our long-read sequencing platforms. This innovative approach was the first of its kind and is now a proven technology used in all fields of life science. Explore each of the SMRT Sequencing Advantages below.
With reads tens of kilobases in length you can readily assemble complete genomes and sequence full-length transcripts.
Explore the benefits of long reads
SMRT Sequencing provides exceptional read lengths without compromising throughput or accuracy. With our two sequencing modes you can optimize your results. Learn more about our Sequencing Modes and the difference HiFi reads make.
Continuous Long-Read Sequencing
Produce long reads with half the data in reads >50 kb with up to 160 Gb of data per SMRT Cell
Data from a 35 kb size-selected E. coli library using the SMRTbell Express Template Prep Kit 2.0 on a Sequel II System (2.0 Chemistry, Sequel II System Software v8.0, 15-hour movie)*.
Highly Accurate Long-Read Sequencing
Generate HiFi reads with half the data >190 kb and up to 400 Gb of data per SMRT Cell
A 20 kb size-selected human library using the SMRTbell Express Template Prep Kit 2.0 on a Sequel II System (2.0 Chemistry, Sequel II System Software v8.0, 30-hour movie)*.
*Read lengths, reads/data per SMRT Cell and other sequencing performance results vary based on sample quality/type and insert size.
Sequencing free of systematic error achieves >99.999% consensus accuracy.
Learn more about high accuracy
With unmatched accuracy, low sequencing-context bias, and accurate mapping of reads, SMRT Sequencing provides the information needed to confidently call and detect all variants.
Consensus accuracy is a function of coverage and chemistry. The data above are based on a haploid bacterial genome run on the Sequel II System (2.0 Chemistry, Sequel II System Software v8.0). HiFi accuracy has similar coverage requirements.
No bias based on GC content means you can sequence through region inaccessible to other technologies.
Discover how uniform coverage lets you see more
Readily sequence through AT-rich or GC-rich regions, highly repetitive sequences, long homopolymers, and palindromic sequences with SMRT Sequencing.
Mean coverage per GC window across a human sample. Data generated with a 20 kb HiFi library on a Sequel II System (2.0 Chemistry and Sequel II System Software v8.0).
Capturing sequence data from native DNA or RNA molecules enables highly accurate long reads with >99% single-molecule accuracy.
See the difference single-molecule resolution makes
Readily achieve high-quality reads to confidently resolve variants of all types.
Generate up to 2 million reads per SMRT Cell 8M with >99% (Q20) 15-20 kb reads.
Data from a 20 kb size-selected human library using the SMRTbell Express Template Prep Kit 2.0 on a Sequel II System (2.0 Chemistry, Sequel II System Software v8.0, 30-hour movie)*.
*Read lengths, reads/data per SMRT Cell 8M and other sequencing performance results vary based on sample quality/type and insert size.
With no PCR amplification step, base modifications are directly detected during sequencing.
Get more from your sequencing with epigenetics
Measurement of variation in polymerase kinetics of DNA base incorporation eliminates the need for chemical modification to detect base modifications. This allows you to capture sequence and epigenetic information in a single experiment.

How Does SMRT Sequencing Work?
SMRT Sequencing enables simultaneous collection of data from millions of wells using the natural process of DNA replication to sequence long fragments of native DNA or RNA.
