Sartorius Stedim Biotech S.A | August 23, 2021
Sartorius Stedim Biotech, a leading international partner of the biopharmaceutical industry, has entered into a partnership with McMaster University to improve manufacturing processes of antibody and virus-based treatments for diseases such as COVID-19, cancers, and genetic disorders.
Using a state-of-the-art multi-column chromatography system provided by Sartorius Stedim Biotech, the McMaster team will "perfect" a process for the purification of therapeutic viruses that is more effective and cheaper than those currently available. This will pave the way for new and more affordable treatments to reach patients with a variety of needs. "Teaming up with Sartorius Stedim Biotech is an exciting opportunity for McMaster Engineering. This research will push the envelope in leading advanced, cutting-edge research in bio-manufacturing," says John Preston, associate dean, research, innovation and external relations in the Faculty of Engineering. "Establishing industry-friendly, collaborative environments is critical in solving real-world problems."
This work aims to support the Sustainable Development Goals (SDG) set out by the United Nations, designed to give our people and planet a better future. More effective bio-manufacturing can make advanced biotherapeutics cost-effective and available to more people globally. "This partnership with McMaster University will lead to impactful research that will make important treatments available at a greater scale. We see this as a way to expand our research development and bring SDG-aligned pharmaceuticals to Canadian and global markets," says Brandon Corbett, research scientist at Sartorius Stedim Biotech.
David Latulippe, associate professor of Chemical Engineering, and Prashant Mhaskar, professor of Chemical Engineering and Canada Research Chair in Nonlinear and Fault-Tolerant Control, are leading this project with Sartorius Stedim Biotech. The collaboration will initially run for four years.
What is chromatography?
Chromatography is an essential purification technology in biomanufacturing. To produce biotherapeutics, scientists use a bioreactor with specialized cell lines and customized growth media. Next, the biotherapeutic must go through a series of purification steps, often with duplicate steps to satisfy the requirements of regulatory bodies.
Sartorius Stedim Biotechs' multi-column chromatography system uses parallel processing strategies to make the process more resource and cost-efficient. "Our ultimate goal is to perfect the downstream chromatography process by combining detailed experimental work with advanced process modelling concepts," says Latulippe. "This way, we can control the outcome and fix the processes on site, as production is happening, so everything is always 'on spec'." Currently, monoclonal antibodies are the leading biotherapeutic being used to fight against COVID-19.
Training the next generation
As part of the partnership, Sartorius Stedim Biotech will provide student training opportunities at their research and development facilities in North America and Europe. Ian Gough, a graduate of McMaster's Chemical and Bioengineering program, has already started working on this project. Gough is a former member of the Summer Studentship Internship program from BioCanRx, a Networks of Centres of Excellence program. Claire Velikonja, a recent chemical engineering graduate from the University of Toronto, will join the team in September.
Both Gough and Velikonja received a Canada Graduate Scholarship from Natural Sciences and Engineering Research Council of Canada (NSERC) to provide additional support for their first year of graduate studies.

Serotiny | March 01, 2022
Serotiny, a leader in high-throughput therapeutic Multi-Domain Protein engineering, and Tessera Therapeutics, a biotechnology company pioneering a new approach in genetic medicines known as Gene Writing technology, today announced a collaboration to engineer programmable Gene Writer proteins. This collaboration will build on Tessera’s innovations in genome engineering technologies and apply Serotiny’s tMDP mining and design expertise to further optimize Tessera’s programmable Gene Writer proteins, capable of making diverse and directed alterations to the genome.
“We’re extremely excited to be working with the Tessera team. It provides Serotiny a unique opportunity to extend the validation of our platform and to continue to advance our efforts in discovering and developing proteins with novel function for the purpose of enhancing the therapeutic utility of next-generation genetic medicines.”
Colin Farlow, J.D., Serotiny’s CEO
Tessera’s Gene Writer candidates can allow the substitution, insertion, or deletion of DNA sequences, as well as the writing of entire genes into the genome, offering the potential for a new category of genetic medicines. By partnering with Serotiny, Tessera will have the ability to identify, screen, and optimize a variety of proteins that can serve as the foundation of future Gene Writer therapies across a variety of disease states.
“Tessera’s mission is to cure disease by writing in the code of life and we’re committed to continuously innovating to improve and expand our Gene Writing platform,” said Geoffrey von Maltzahn, PhD, co-founder and CEO of Tessera. “Our R&D engine seeks to learn from billions of years of mobile genetic element evolution to generate novel Gene Writing systems with the ability to solve important challenges in genetic medicine. Serotiny’s multi-domain engineering expertise has the potential to further optimize our Gene Writer protein libraries and we’re delighted to partner with the Serotiny team.”
Under terms of the agreement Serotiny will receive an upfront payment and is eligible for certain future consideration, contingent upon the collaboration achieving pre-specified performance thresholds.
Serotiny is a pre-clinical discovery company building better gene and cell therapies through high-throughput engineering of therapeutic Multi-Domain Proteins (tMDP) such as Chimeric Antigen Receptors (CARs), CAR alternatives, accessory proteins, and next generation gene editors. At the heart of Serotiny’s technology is a discovery platform that harmonizes computationally aided protein design, high-throughput cellular assays, and next generation sequencing.

About Tessera’s Gene Writer platform
Tessera’s Gene Writer proteins are based on nature’s genome architects, Mobile Genetic Elements (MGEs)—the most abundant class of genes across the tree of life, representing approximately half of the human genome. Tessera has evaluated tens of thousands of natural and synthetic MGEs to create Gene Writer candidates in multiple categories including
RNA Gene Writer proteins that use target-primed reverse transcription (TPRT), which evolved in a class of MGEs known as retrotransposons. TPRT uses three steps to make an alteration: DNA-binding, DNA-nicking (without double strand breaks to DNA), and reverse transcription. Tessera’s Gene Writing technology requires a DNA sequence match at all three steps, reducing the likelihood of off-target editing. Tessera’s Gene Writer components can be delivered as therapeutic compositions comprised of RNA molecules within lipid nanoparticles, offering the potential for scalable, re-dosable genetic medicines with the ability to make the full spectrum of small and large edits to genome, from single or multi-base pair corrections, insertions, deletions, to writing entire genes.
DNA Gene Writer proteins are derived from recombinases and integrases and enable permanent integration of whole-gene sequences, delivered as DNA, into the genome without the introduction of double-strand breaks. This opens up the potential for treating pediatric patients leveraging validated delivery modalities
Tessera’s research engine further optimizes the discovered Gene Writer candidates for efficiency, specificity, and fidelity—essentially compressing eons of evolution into a few months.
