QS-21 fraction
In stock
Description
The 21st significant fraction isolated from Quillaja saponaria extract via Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC).
Exhibits potent immunostimulatory properties, simultaneously triggering robust humoral immunity (antibody production) and intense cell-mediated responses (Th1 and CD8+ T cell activity). It also demonstrates a powerful synergistic effect when combined with the QS-7 fraction.
