If you are making a cell-based vaccine, you can consider using our recombinant Insulin to promote cell growth and viability.
Bacterial, polysaccharide-based vaccines
- Polysaccharide vaccines are a unique type of inactivated subunit vaccine composed of long chains of sugar molecules, that make up the surface capsule of certain bacteria. These vaccines target e.g. pneumococcal and meningococcal diseases.
- Polysaccharide vaccines are commonly found in standard children vaccination programs.
- CTAB (Cetrimonium Bromide) is recommended by the WHO in bacterial vaccine manufacturing as a purification agent for polysaccharide vaccines.
- CTAB serves as a surfactant in a buffer system, to remove membrane lipids and promote cell lysis, to “free-up” the polysaccharides.
- CTAB can be used in downstream processing of viral vaccines, for example influenza vaccines.
- CTAB is used as a cationic detergent to isolate the antigenic agents, e.g. influenza HA proteins.
- It can be used in egg-based, cell-based and recombinant (DNA) vaccines for downstream purification.
- Sub unit isolation can be done using a mixture of Tween 80 with CTAB, to separate RNP (Ribonucleoprotein) particles from the surface antigen proteins by centrifugation.
