Single-cell DNA Analysis: Driving Dynamic Changes in the Treatment of Cancer

LAURA ELIZABETH LANSDOWNE | April 26, 2019 | 88 views

Complex diseases, such as cancer evolve, so understanding genetic variability at the single-cell level is vital. Ensuring researchers have the tools to unlock single-cell biology enables the discovery, development, and delivery of precision medicine.

Top 10 biotech IPOs in 2019

Article | July 14, 2022

The big question at the start of 2019 was whether the IPO window would stay open for biotech companies, particularly those seeking to pull off ever-larger IPOs at increasingly earlier stages of development. The short answer is yes—kind of. Here’s the long answer: In the words of Renaissance Capital, the IPO market had “a mostly good year.” The total number of deals fell to 159 from 192 the year before, but technology and healthcare companies were standout performers. The latter—which include biotech, medtech and diagnostics companies—led the pack, making up 43% of all IPOs in 2019. By Renaissance’s count, seven companies went public at valuations exceeding $1 billion, up from five the year before

Cell Out? Lysate-Based Expression an Option for Personalized Meds

Article | August 16, 2022

Cell-free expression (CFE) is the practice of making a protein without using a living cell. In contrast with cell line-based methods, production is achieved using a fluid containing biological components extracted from a cell, i.e., a lysate. CFE offers potential advantages for biopharma according to Philip Probert, PhD, a senior scientist at the Centre for Process Innovation in the U.K.

Closing bacterial genomes from the human gut microbiome using long-read sequencing

Article | July 16, 2022

In our lab, we focus on the impact of the gut microbiome on human health and disease. To evaluate this relationship, it’s important to understand the particular functions that different bacteria have. As bacteria are able to exchange, duplicate, and rearrange their genes in ways that directly affect their phenotypes, complete bacterial genomes assembled directly from human samples are essential to understand the strain variation and potential functions of the bacteria we host. Advances in the microbiome space have allowed for the de novo assembly of microbial genomes directly from metagenomes via short-read sequencing, assembly of reads into contigs, and binning of contigs into putative genome drafts. This is advantageous because it allows us to discover microbes without culturing them, directly from human samples and without reference databases. In the past year, there have been a number of tour de force efforts to broadly characterize the human gut microbiota through the creation of such metagenome-assembled genomes (MAGs)[1–4]. These works have produced hundreds of thousands of microbial genomes that vastly increase our understanding of the human gut. However, challenges in the assembly of short reads has limited our ability to correctly assemble repeated genomic elements and place them into genomic context. Thus, existing MAGs are often fragmented and do not include mobile genetic elements, 16S rRNA sequences, and other elements that are repeated or have high identity within and across bacterial genomes.

Selexis Cell Line Development Strategies

Article | February 11, 2020

In today’s biotechnology landscape, to be competitive, meet regulations, and achieve market demands, “we must apply Bioprocessing 4.0,” said Igor Fisch, PhD, CEO, Selexis. In fact, in the last decade, “Selexis has evolved from cloning by limiting dilution to automated cell selection to nanofluidic chips and from monoclonality assessment by statistical calculation to proprietary bioinformatic analysis,” he added. Single-use processing systems are an expanding part of the biomanufacturing world; as such, they are a major component of Bioprocessing 4.0. “At Selexis, we use single use throughout our cell line development workflow. Currently, we have incorporated single-use automated bioprocessing systems such as ambr® and the Beacon® optofluidic platform for accelerated cell line development. By using these systems and optimizing our parameters, we were able to achieve high titers in shake flasks. Additionally, the Beacon systems integrate miniaturized cell culture with high-throughput liquid handling automation and cell imaging. This allows us to control, adjust, and monitor programs at the same time,” noted Fisch.

IsoPlexis Acquired a Large Portfolio of DNA and RNA Sequencing to Enable Integrated Single-Cell Sequencing and Proteomic Solutions

IsoPlexis | May 26, 2021

IsoPlexis, the leader in functional single-cell proteomics, announced today the acquisition of a large intellectual property portfolio containing 86 patents related to DNA and RNA sequencing. These nucleic acids and sequencing technologies will be immediately integrated with IsoPlexis' single-cell proteomics platforms, enabling a variety of next-generation tests that include numerous 'omic modalities from every single cell. This is the next step in the company's roadmap, enabling researchers to make far earlier connections in their genomic studies, straight to the proteome, which determines each organism's in vivo dynamic biology. The acquired assets will allow IsoPlexis' proprietary proteomics technologies to be integrated with newer proprietary sequencing-based technologies. The asset acquisition adds to IsoPlexis' ongoing efforts to assist its customers in more effectively simplifying complex biology to accelerate the creation of more personalized and curative advanced medicines from bench to bedside. Isoplexis' growing patent portfolio of 153 total patents filed and issued globally will now include sequencing methodologies, allowing for a new level of resolution into the connections between the genome and the proteome of cancer immunology, cell and gene therapy, neurological disease, and other areas. IsoPlexis' proprietary functional proteomics platform is the first to fully characterize and link cellular function to patient outcomes, treatment response, or disease progression using both proteomics and single-cell biology. The single-cell proteomics platform from IsoPlexis, which comprises instruments, chip consumables, and software, offers an end-to-end solution for providing a more complete view of protein function at the cellular level. The platform has been quickly embraced by the top 15 global biopharmaceutical companies in terms of revenue, as well as over half of the comprehensive cancer centers in the United States, to develop more durable therapeutics, overcome therapeutic resistance, and predict patient responses for advanced immunotherapies, cell therapies, gene therapies, vaccines, and regenerative medicines. ABOUT ISOPLEXIS IsoPlexis is a life science technology company that develops solutions to accelerate the development of curative medicines and personalized therapeutics. Our award-winning single-cell proteomics systems reveal unique biological activity in small subsets of cells, allowing researchers to connect to in vivo biology more directly and develop more precise and personalized therapies. Our integrated systems, which were named top innovation or design by Scientist Magazine, Fierce, BIG Innovation, Red Dot, and a variety of other magazines, are used globally to advance the field of single-cell biology into new 'omic possibilities, as our customers generate solutions to overcome the challenges of complex diseases and therapeutics. Our products have been used by researchers all over the world, including the top 15 pharmaceutical companies in the world and 45% of comprehensive cancer centers in the United States.
