QS-21-Api
NLRP3 Activator
QS-21-Api is a potent NLRP3 activator that functions as an immunostimulatory saponin, enhancing vaccine efficacy as an adjuvant. It stimulates both Th2 humoral and Th1 cell-mediated immune responses by acting on antigen presenting cells (APCs) and T cells. Through the activation of the NLRP3 inflammasome, QS-21-Api prompts the release of caspase-1 dependent cytokines, including IL-1β and IL-18, making it a valuable tool for research in immunology and vaccine development.
