This unit specializes in high potent products (cytotoxics), biological products (monoclonal antibodies, proteins, antibody-drug conjugation, viruses), and narcotic substances. The site accommodates the entire drug manufacturing process, from formulation to pilot-scale production and transfer to production units.
