Overview of Cornerstone® Biomanufacturing Development Services

Are you seeking speed and scalability for your virus particle and large molecule process, from preclinical and PI to PIII and beyond?
Do you lack expertise and capabilities when it comes to AAV, pDNA or mRNA purification and analysis?
Are you looking to improve or fix an existing large biomolecule process?
No matter if you are a large company or a start-up. We have got your back!

Downstream part of the process is a complex matrix full of interdependent parameters where optimization is not straightforward, so experience provides the quickest way to identify the key quality attributes for your unique product and optimizing them for best performance. This allows for significant time, labour and opportunity cost savings, permitting your team to focus on bringing your product to clinic and market.

Our Cornerstone® Biomanufacturing Development Services are result of 25 years of hands-on experience with the most challenging biopharmaceutical products and offer a comprehensive approach of integrated process development solutions and novel technology designed to improve the robustness and yield of AAV, pDNA, mRNA, exosomes and other Advanced therapy medicinal products (ATMPs) production, while improving the safety of therapeutic products.
