MENLO PARK, Calif., April 29, 2014 (GLOBE NEWSWIRE) — Pacific Biosciences of California, Inc., (Nasdaq:PACB) and HistoGenetics, a global leader in Human Leukocyte Antigen (HLA) sequence-based typing (SBT), announced today that HistoGenetics has selected the PacBio DNA Sequencing platform for its unique ability to sequence full-length HLA genes and to provide fully phased HLA alleles. HistoGenetics has purchased two PacBio RS II DNA Sequencing systems, which will be used for HLA typing and will be evaluated as potential replacements for Sanger sequencing.
Comprehensive characterization of an individual’s HLA type is important for research in tissue transplantation matching, autoimmune disease-association studies, drug hypersensitivity research, and other applications. The HLA genes are highly polymorphic, containing thousands of alleles that code for proteins that are important for recognizing foreign antigens. Accurate phasing of HLA polymorphisms using Sanger and short-read sequencing technologies has previously required confirmation, incurring additional expense. These methods also suffer from ambiguous calls when imputation data is required. The long read lengths (tens of thousands of bases) provided by PacBio sequencing are ideally suited for accurate allele-level genotyping since unambiguous allele phasing is critical for high-resolution allele assignment.
“As a leader in the HLA typing market, we aggressively seek out technologies that can accurately analyze this complex region of the genome. With its industry-leading read lengths, accuracy, and fast turnaround time, PacBio’s sequencing platform is exactly what this market needs,” said Dr. Nezih Cereb, Chief Executive Officer and co-founder of HistoGenetics. “We are eager to use our new PacBio RS II machines to get comprehensive, novel views of the HLA region and other genes relevant to immunology, such as KIR.”
Michael Hunkapiller, President and CEO of Pacific Biosciences commented: “The PacBio RS II system is the only commercial sequencer that can work through highly complex regions of the genome, and customers routinely tell us that it enables them to see genetic elements they have never been able to see before. As HistoGenetics applies this technology for HLA typing research, we believe they too will find novel insights that will be immensely useful to the biomedical research community.”
