Writing the Future of Biologics to Discover and Optimize Antibodies

With our unique DNA writing technology, Twist Biopharma is accelerating the way our partners discover and optimize antibody therapeutics. We have decades of synthetic antibody library design and selection expertise and have the ability to write any DNA sequence to enable faster, better discovery and development. Using our precise, rational, expertise in library fabrication, we can create libraries in a fundamentally different way that allow us to address tough targets, e.g. GPCRs. Since we are a DNA product company, we…

Understanding and Controlling Raw Materials Variation in Cell Culture Media

The FDA requires biopharmaceutical manufacturers to understand and control sources of variation according to the risks they present to process and product. Cell culture media and feeds have been shown to affect cellular performance, product quality, or both. The evolution of media formulas to those that are serum-free and chemically defined poses both a challenge and an opportunity. The challenge is identifying which of the many components have the greatest impact on cells and the molecules they produce. The opportunity…

Analytical Power Tools Open Upstream Bioprocessing Bottlenecks

The blockbuster success of antibody-based therapeutics for autoimmune diseases, inflammatory diseases and immuno-oncology accelerated the high stakes monoclonal antibody (mAb) development race. Clone selection is a significant upstream bottle-neck slowing bench-to-bedside development progress for new mAb-based therapeutics. Cy-Clone™ PLUS, a validated assay kit accelerates human mAb production cell-line generation, significantly reducing the time to industrial-scale productivity. Cy-Clone PLUS assay combined with the Intellicyt® iQue platform and integrated ForeCyt® Software are powerful analytical tools that inform rapid go/no-go decisions with multiparameter,…

Streamlining the Antibody Discovery Workflow at ModiQuest Research

With breakthroughs in molecular engineering and antibody humanization, monoclonal antibodies (mAbs) are one of the fastest-growing classes of biopharmaceuticals for most clinical indications. In 2017, 10 therapeutic monoclonal antibodies were approved in the EU or US with nine additional candidates under regulatory review and 60 in phase III clinical trials 1. mAbs are the backbone of many treatment modalities including unconjugated therapeutic antibodies, antibody drug conjugates, bispecific antibodies and CAR-T cell therapy. Many of the approved antibody drugs engage the…

The Challenge of Building Better, Lower Cost Biologic Drugs Faster

A critical factor for both the lowering in costs of development as well as costs of production for biologic therapies is to develop a cell line that grows faster and produces larger amounts of vaccines and drugs using low cost synthetically defined media. Dyadic’s industrially proven C1 gene expression platform creates a stable cell line in a shortened timeline, reducing the time from gene fragment to stable cell line by 50% when compared to CHO cells. C1 stable cell lines…

Culture of 3D Cell Aggregates in Perfusion in a DASbox® Mini Bioreactor System

Three-dimensional (3D) cell aggregates are of great interest for many applications, including disease modeling, drug toxicity assessment, and manufacturing of stem cell-based products. Stirred-tank bioreactors are promising culture systems for 3D cell aggregates, as they allow efficient establishment and maintenance of cell aggregates, process monitoring and control, and process scale-up to larger volumes. Furthermore, they can be operated in perfusion mode, which allows 3D cell aggregates to be sustained longer than in traditional batch cultures. Researchers at the Instituto de…

EZ BioPac® Powder Transfer Gets Your Biologic to Market Faster, with Less Risk

This whitepaper quantifies how one simple change can drastically reduce the time it takes to get biologics manufactured. Getting media and buffer into large-scale, continuous bioprocessing has been burdensome, time consuming and messy. Upgrading to modern single-use powder handling in your process gets your product to market without time wasted on complicated weigh and dispense steps, cleaning validations, or worries about powder in the air and in the room.

Bioprocessing in a Time of Digital Transformation

eve® is a modular software system for bioreactors and incubator shakers, rethinking bioprocess control to meet the needs of modern users: Fast, secure access to data via a web browser from anywhere, using a range of devices The move to Big Data Analytics for process data analysis A single platform for different types of information required by different users e.g. researchers, production and quality assurance A browser-based approach to accessing this information makes considerations such as operating system, size of…

Gram Scale Transient Antibody Production and Stable Cell Line Generation Using Flow Electroporation™ Technology

In recent years researchers have turned to transient gene expression (TGE) as an alternative to CHO stable cell line production for early stage antibody development. Despite advances in transfection methods and culture optimization, the majority of CHO-based TGE systems produce insufficient antibody titers (low mg/L level) for full use within the biotherapeutic development pipelines. MaxCyte’s delivery platform for cell engineering is based on Flow Electroporation™ technology and provides a universal means of fully scalable, highly efficient CHO-based TGE for the…
