Saponin vaccine adjuvant
Saponin vaccine adjuvant
Quil‑A® adjuvant is a saponin adjuvant produced under GMP by Brenntag Biosector, a leader in the global vaccine adjuvants market, and purified by them through a proprietary process that ensures consistency and immunostimulatory potential.
Quil-A® adjuvant is used in a wide variety of veterinary vaccines, as well as in immunological research into human and veterinary applications [1,2]. Quil-A® adjuvant contains the water-extractable fraction of saponins from the South-American tree, Quillaja saponaria Molina.
These saponins belong to the group of triterpenoid saponins, that have a common triterpenoid backbone structure.
Saponins induce a strong adjuvant response to T-dependent as well as T-independent antigens . Saponins also induce strong cytotoxic CD8+ lymphocyte responses and potentiate the response to mucosal antigens [2,3]. When combined with cholesterol and phospholipids to form ISCOMs (immunostimulatory complexes), Quil-A® adjuvant can activate both the cell‑mediated and the antibody-mediated immune responses to a broad range of viral, bacterial, parasitic and tumor antigens .
InvivoGen products are for research purposes only; they are not for use in humans.
Quil-A® is a trademark that belongs to Croda (formerly known as Brenntag Biosector A/S) and is registered in a large number of countries and regions worldwide.

Quil-A® adjuvant is provided lyophilized:
- 1 g lyophilized Quil-A® adjuvant
Product is not sterile. However, prior to lyophilization Quil-A® adjuvant has been passed through a 0.22 micron filter.
Hence, the product has very few colony forming units (CFU).
Quil-A® adjuvant is shipped at room temperature.
Lyophilized Quil-A® adjuvant can be stored from -25 °C to 25 °C.Back to the top
