SIRION Biotech started its business in 2005 in Munich, with the goal of sparking a new generation of viral vector technologies for cell and gene therapy, and vaccine development. This meant building novel, all-encompassing viral vector platforms for adeno-associated virus (AAV), lentivirus (LV), and adenovirus (AV).

SIRION Biotech is now the leading European developer and manufacturer of viral vectors for research and preclinical applications. To date we have completed over 2000 projects of all sizes, working closely with over 600 clients from academia and industry, 400 of whom have ordered multiple times. We also offer LentiBOOST®, a highly effective lentiviral transduction enhancer for therapeutic cell types like CAR-T cells and CD34+ hematopoietic stem cells. LentiBOOST® is currently included in more than 20 Phase III and I/II clinical trials.

We are committed to enabling our partners to develop the most successful vectors for their applications. We guide our customers through the entire Cell & Gene Therapy value chain – from capsid evolution and clinical vector design to reduce vector dose and improve therapeutic success, to supporting them with our process and development experience and manufacture of high-quality clinically compliant viral vectors for late preclinical applications.

R&D Collaborations

SIRION Biotech offers expert support for all stages of your viral vector project, whether you are working with AAV, Lentivirus, or Adenovirus. Each project has an experienced and dedicated manager to work with you to develop the ideal vector for your needs and customize the scale and QC procedures to meet your requirements.

We have well established platform manufacturing processes, and are constantly working on improvement of all upstream and downstream process stages. Our high quality standards ensure repeat customers and client recommendations.

If you are moving towards cell or gene therapy applications, our Clinical Support team can help with vector design for optimum safety and efficacy, and our GMP Alliance team will help transfer your project and assays to the CMO of your choice.

Our laboratories are located in Munich, Germany, and ideally situated to serve the Spanish viral vector market.

Our clients are researchers and product developers working with AAV, Lentivirus, or Adenovirus vectors for gene transfer. They can be found in both academic and research institutes, and commercial companies pursuing drug discovery or developing cell and gene therapies.

Clients may have very little knowledge of viral vectors and rely on our highly qualified development teams or may be experts in viral vector technologies looking for a reliable, high quality, manufacturing partner.

Our clients share a desire to develop the ideal vector and have it manufactured to the highest quality standards.
