Description
QS-21 is a purified plant extract that enhances the ability of the immune system to respond to vaccine antigens. It is derived
from the Soap bark tree (Quillaja saponaria), which is native to the country of Chile. The extract contains water soluble triterpene glucoside compounds, which are members of a family of plant-based compounds called saponins. QS-21 Stimulon activates key components of the immune system including cellular (T cell mediated) and humoral (antibody mediated) immunity. Both of these components of the immune system are often necessary to enable the body to heal or protect itself. Stimlon has been studied in over 120 clinical trials involving approximately 50,000 patients during nearly 15 years of development. QS-21 Stimulon is currently a key adjuvant component in 20 clinical development programs of Agenus, GSK and J&J.
