MENLO PARK, Calif., April 27, 2015 (GLOBE NEWSWIRE) -- Pacific Biosciences of California, Inc., (Nasdaq:PACB) provider of the PacBio® RS II Sequencing System, today announced the introduction of several new solutions for targeted sequencing applications.
The company has introduced a new workflow that combines Roche NimbleGen's SeqCap EZ enrichment technology with large DNA fragments (up to 6 kb) and PacBio's Single Molecule, Real-Time (SMRT®) Sequencing to provide a more comprehensive view of variants, transgene integration sites, and haplotype information over multi-kilobase contiguous regions. The long fragments capture haplotype information that provide a more inclusive view of the targeted region of interest, allowing a comprehensive look at variants in exons, introns and intergenic regions, as well as generation of accurate haplotypes.
In a recent study by Richard Gibbs and colleagues from Baylor College of Medicine, this new enrichment method was used for de novo sequencing and detection of structural variation involved in human genetic disease. The study, titled "PacBio-LITS: a large-insert targeted sequencing method for characterization of human disease-associated chromosomal structural variations," was published in BMC Genomics.1
"The use of NimbleGen Sequence Capture technology to enrich large DNA molecules for targeted sequencing on the PacBio platform leverages the advanced capabilities of both systems to achieve unprecedented efficiency for targeted genetic phasing and structural variant elucidation," said Rebecca Selzer, Ph.D., President, Roche NimbleGen (Madison, Wisconsin). "The ability to focus SMRT Sequencing onto discrete regions of interest within a genome demonstrates that the technical advantages inherent in long, single molecule sequencing can be part of a higher-throughput analysis strategy."
PacBio also announced the launch of two multiplexing workflows and associated products for barcoding samples prior to running on SMRT Cells. The new barcoding kits allow customers to pool many samples and thus reduce the cost per sample and the total time for sample preparation. By employing the barcoding strategies, researchers can efficiently focus on even more defined genomic regions. And by barcoding samples, researchers have the flexibility to multiplex samples or targets within a sample or a combination of both.
Kevin Corcoran, Senior Vice President of Market Development for Pacific Biosciences commented: "With the combined PacBio/Roche NimbleGen solution we have demonstrated very efficient capture and sequencing that provides uniform coverage over multi-kilobase regions of the genome. The new barcoding methods allow a greater numbers of samples to be studied simultaneously and also improve the efficiency of SMRT Sequencing, by increasing SMRT Cell sample capacity and streamlining the workflow."
