The world is moving at a fast pace, isn’t it? Climate shifts, growing populations, and changing ecosystems are stacking up some serious challenges for species all over the planet, including our own. Researchers like you, working to figure out the complexities of plant and animal biology, are the key to protecting biodiversity and sustaining agriculture in this changing world. With advances in long-read sequencing technology, we’ve got a sharper toolkit. Now, we can detangle complex polyploid genomes and sequence through challenging regions like never before. These insights are crucial for con ..read more

Alternative splicing occurs when exons from the same gene combine in different ways, resulting in different (but related) RNA transcript isoforms, which in turn create different proteins with distinct structures and functions. Despite being “alternative,” this process isn’t rare. Up to 95% of genes in the human genome undergo alternative splicing. The resulting RNA diversity plays a key role in human biology, as different isoforms can be drivers of disease. For this reason, full-length isoform sequencing is a powerful tool that allows investigators to look at how alternative splicing disrupts ..read more

  The complexities of cancer biology are famously tricky to decipher. Peering into the murky cancer genome and making sense of tumor mechanisms has long been the goal of researchers everywhere, and technology has often felt one step behind. But the genomics landscape is evolving quickly. Now, researchers no longer need to be limited by the sequencing technology of yesterday. Today, cancer researchers are moving away from using only short-read sequencing and instead harnessing the power of long reads to see into the cancer genome, transcriptome, and epigneome to help characterize tumor b ..read more

  Hearing “the end of the beginning” or “the dawn of a new era” might sound like a grandiose way to describe a scientific milestone. Would it surprise you to learn these phrases were used in 2003 to celebrate the completion of the Human Genome Project? Despite the fanfare, only 92% of the human genome had been mapped then. Now, let’s leap to 2022. The once elusive 8% has been brought to light, thanks to HiFi sequencing, culminating in the first-ever complete “telomere-to-telomere” assembly of a human genome. Such an accomplishment might seem beyond the reach of everyday research, reserv ..read more

  In the fast-evolving landscape of genomics, the pace can be dizzying, and the fear of falling behind is real. Genomic research undergoes constant change, so if you want to keep your finger on the pulse of what’s available, you need to know the facts. Not too long ago, long-read sequencing was an emerging technology. Today, PacBio HiFi long reads are routinely used across the world to sequence thousands of genomes, epigenomes, and transcriptomes. HiFi sequencing applies to projects large and small, from academic research endeavors to large-scale population health studies. The rate of t ..read more

For years, exome sequencing has been a popular method for identifying disease-causing variants, both in clinical and research settings, due to its relative affordability and practicality when compared to whole-genome sequencing. However, because the exome is confined to only protein-coding regions of the genome (about 1.5% to 2%), it is inherently limited.1 That limitation has long been an acceptable trade-off for cost and throughput reasons, but it no longer needs to be. HiFi whole-genome sequencing on the Revio system not only captures a more complete picture of genetic variation, both in i ..read more

  Faculty at the Translational Genomics Research Institute (TGen) at City of Hope were among some of the first to see the promise of the Onso system and sequencing-by-binding (SBB) chemistry for advancing liquid biopsy research. PacBio recently had the opportunity to sit down with Cristian Tomasetti, Director of the Center for Cancer Prevention + Early Detection at City of Hope and TGen, to discuss Onso and SBB performance in the development of new cutting-edge liquid biopsies by the organization. Key takeaways: The team at TGen is developing liquid biopsy assays based on fragmentomics ..read more
