What is PacBio sequencing?

What is PacBio sequencing?

PacBio sequencing captures sequence information during the replication process of the target DNA molecule. The template, called a SMRTbell, is a closed, single-stranded circular DNA that is created by ligating hairpin adaptors to both ends of a target double-stranded DNA (dsDNA) molecule (Figure 1) [2].

What is the difference between PacBio and Illumina sequencing?

PacBio provides longer read length than Illumina's short-length reads. Longer reads offer better opportunity for genome assembly, structural variant calling. It is not worse than short reads for calling SNP/indels, quantifying transcripts. Sounds like PacBio can do whatever Illumina platform can offer.

Is PacBio more accurate than Illumina?

PacBio reads typically have a really high error rate (~15% compared with ~0.1% for Illumina.) However, their errors tend to be random, so if the same region is sequenced several times, the errors average out resulting in a “consensus” sequence.

What is PacBio HiFi?

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.

Does PacBio sequencing use DNA polymerase?

PacBio SMRT Sequencing uses the innovation of ZMW to distinguish the ideal fluorescent signal from the strong fluorescent backgrounds caused by unincorporated free-floating nucleotides. The binding of a DNA polymerase and the template DNA strand is anchored to the bottom glass surface of a ZMW.

Is Illumina sequencing real time?

Real-Time Analysis (RTA) software operates during cycles of sequencing chemistry and imaging, providing base calls and associated quality scores representing the primary structure of DNA or RNA strands. This built-in software performs primary data analysis on Illumina sequencing systems automatically.

What does Sanger sequencing do?

Sanger sequencing, also known as the “chain termination method”, is a method for determining the nucleotide sequence of DNA. The method was developed by two time Nobel Laureate Frederick Sanger and his colleagues in 1977, hence the name the Sanger Sequence. To review the general structure of DNA, please see Figure 2.

Why does PacBio have high error rate?

The error rate of raw PacBio data is 13–15%, as the signal-to-noise ratio from single DNA molecules is not high 3. To increase accuracy, the PacBio platform uses a circular DNA template by ligating hairpin adaptors to both ends of target double-stranded DNA.
