The company's first scientific instrument, called the PacBio RS, was released to a limited set of customers in late 2010., with full commercial release in early 2011. [17] [8] Sequencing provider GATC Biotech was selected by Pacific Biosciences as its first European service provider in late 2010. [18]
The DNA sequencing is done on a chip that contains many ZMWs. Inside each ZMW, a single active DNA polymerase with a single molecule of single stranded DNA template is immobilized to the bottom through which light can penetrate and create a visualization chamber that allows monitoring of the activity of the DNA polymerase at a single molecule level.

These sequencing technologies were used to collect information: Pacific Biosciences (PacBio) high-fidelity (HiFi) with 39.7× HiFi sequence depth of coverage, Oxford Nanopore Technologies (ONT) long-read sequencing, and Bionano optical maps and high-coverage Hi-C Illumina short-read sequencing. To analyze the 18 additional samples, they ...
Assembly of single cell data is difficult due to non-uniform read coverage, variation in insert length, high levels of sequencing errors and chimeric reads. [ 8 ] [ 12 ] [ 13 ] Therefore, the new algorithmic approach, SPAdes, was designed to address these issues.
PacBio's (PACB) latest acquisition is expected to deliver the most advanced blend of sequencing solutions to transform the genomics landscape.
Sequencing technologies vary in the length of reads produced. Reads of length 20-40 base pairs (bp) are referred to as ultra-short. [2] Typical sequencers produce read lengths in the range of 100-500 bp. [3] However, Pacific Biosciences platforms produce read lengths of approximately 1500 bp. [4] Read length is a factor which can affect the results of biological studies. [5]
The workflow of a typical hybrid genome assembly experiment using second- and third-generation sequencing technologies. Figure adapted from Wang et al., 2012 [14]. One hybrid approach to genome assembly involves supplementing short, accurate second-generation sequencing data (i.e. from IonTorrent, Illumina or Roche 454) with long less accurate third-generation sequencing data (i.e. from PacBio ...
