Process Development

Our Approach to Process Development

Process development is critical for the success of commercially-viable, safe products. At Andelyn Biosciences, we use a set of rigorous process development guidelines to establish, implement, and improve our manufacturing processes.

By tightly controlling our manufacturing processes, we ensure that your products are made in an aseptic environment, meet your quality specifications, and maintain this quality when created at scale.

Not only that, but through every step of process development, we work closely with your team to ensure that we prioritize quality and reproducibility of your products – as well as affordability when manufacturing at scale.

Creating an AAV, plasmid, or other product from a research lab is one thing, but a lot can change when processes are being established to create the product at an industrial scale. Andelyn uses a controlled environment, advanced equipment, and a systemic approach to process development to ensure your products remain consistently high in quality as they’re scaled for commercial manufacturing.
