QS-21

QS-21
Product Description

QS-21 is an isomeric saponin extracted from the bark of the soap tree (Quillaja Saponaria). It consists of one or more hydrophilic glycoside groups connected to lipophilic triterpenoid derivatives, and contains about 65% QS-21-apiose and 35% QS-21-xylose. Its function is to stimulate antibody-based and cell-mediated immune responses, produce high-titer antibodies (IgG2a, IgG2b and IgG1) and antigen-specific cytotoxic T lymphocytes. It has been used in multiple marketed vaccines and is also the preferred adjuvant in many vaccine clinical trials.
