From research through commercialization, ANGUS offers a comprehensive portfolio of high-purity, cGMP-compliant* buffers and biochemicals, as well as specialty cell culture media, cell lines, molecular tools, and contract services through our recent acquisition of Expression Systems. This combination of ANGUS and Expression Systems strengthens our ability to deliver the essential products and world-class quality that enable consistent, reliable upstream and downstream processing.
Our buffer manufacturing expertise spans nearly 70 years, starting with the invention of TRIS AMINO™ molecule. Today, as the world’s largest and only fully integrated manufacturer of TRIS AMINO tromethamine buffers, ANGUS is uniquely positioned to provide you with 100% traceability and the most secure, sustainable supply available on the market. This deeply rooted manufacturing expertise applies to every buffer we make – from cGMP-compliant grades of TRIS AMINO, TRIS AMINO™ Hydrochloride and HEPES to general purpose buffer grades – we have you covered.
In addition to our growing portfolio of ANGUS-produced buffers, we also now offer Expression Systems’ innovative cell culture media, cell lines, molecular tools, reagents and contract services used to support the baculovirus expression platform widely used in gene therapy and general research. Expression Systems, now an ANGUS company, operates from a central manufacturing, R&D and warehouse location in Davis, California, and is cGMP-compliant and ISO 13485 certified for its manufacturing and research activities.
ANGUS also offers salts, amino acids, vitamins and other biochemicals from the world’s leading producers delivered through a secure, transparent supply chain. All producers are qualified through a rigorous evaluation and audit process to ensure all products meet our demanding quality and regulatory standards.
