Description |
combination vaccine adjuvant that includes AS01-mimic, Immune Stimulating Complex (ISCOM) with a TLR4 agonist that induces a mixed Th1/Th2 response |
|
Stage of Development |
Research |
|
Location Licensed |
US (Massachusetts institute of technology) |
|
Host Species for Testing |
3 |
|
Components |
QS-21 saponin and monophosphoryl lipid A and cholesterol and phospholipids |
|
Storage |
4 C in liquid form or frozen at -20C in PBS pH 7.4 or 6.5 |
|
Preparation |
solubilized in micelles of surfactant MEGA-10 then diluted below CMC, then self-assembled using QS-21 |
|
Function |
robust production of cytokines and chemokines in vaccine site-draining lymph nodes, enhances lymphatic transport of antigen, and increases antigen accumulation in draining lymph nodes |
