CTAB or Cetrimonium bromide can be used for several purposes in the pharma industry. As a pharmaceutical ingredient, it is an antiseptic agent with various antibacterial, antifungal and other antimicrobial properties. It is used in various products such as throat lozenges and antiseptic topical gels and creams for a range of purposes. As a processing aid or auxiliary, it can be used in the downstream vaccine manufacturing process, typically for both bacterial polysaccharide vaccines and viral vaccines (e.g. influenza).
Tromethamine can be used in biopharmaceutical buffer formulations (both upstream and downstream), electrophoresis separations and diagnostic reagent formulations. Tromethamine is especially useful in downstream purification processes.
HEPES can be used in cell culture media, in biopharma buffer formulations (both upstream and downstream), and in diagnostic reagents. HEPES based buffers are used in purification bioprocesses of antibodies, bioactives, proteins and growth factors.
