What is CTAB?

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/ancillary, it can be used as a surfactant in the downstream vaccine manufacturing process, for both bacterial polysaccharide vaccines and viral vaccines (e.g. influenza).

CTAB is crucial in breaking up cell membrane, as it initiates cell lysis to isolate antigenic material. It protects from co-precipitated membrane lipids, allowing for efficient antigen isolation with high yields.

CTAB is also employed in isolation/extraction of DNA and in manufacturing of novel Gene Therapies, e.g. as a non-viral vector.
